A Spiffy Upgrade for the Ruger 10/22

In about ten minutes, you can replace the standard Ruger 10/22 trigger and magazine release with an upgraded model.

In about ten minutes, you can replace the standard Ruger 10/22 trigger and magazine release with an upgraded model.

I love the Ruger 10/22 rifle. It’s a sweet handling little semi-automatic that you’ll enjoy whether young or old, experienced shooter or not. It qualifies as one of those guns you’ll use your whole life, then pass down to the next generation.

I have to qualify just a bit as there is one part I don’t really care for. That’s the magazine release. The Ruger 10/22 comes standard with a 10-round rotary magazine that fits completely inside of the stock. You can get larger magazines of course, but part of what makes the 10/22 special is its 10-round capacity with no extra bulk. It’s the standard magazine release lever that just doesn’t sit right with me. It’s a non-traditional curved lever, in front of the trigger guard, that you push forward to drop the magazine from the rifle. I find it somewhat awkward and non-intuitive.

One of the neat things about the Ruger 10/22 is that it’s been so popular, that companies have developed all sorts of aftermarket accessories and upgrades. For example, you can replace that standard magazine release lever. Better yet, you can get a modular unit that upgrades the trigger and improves magazine release.

I’ve got a standard Ruger 10/22 Carbine that’s itching for some custom work, so I decided to upgrade the trigger and magazine release with a Timney Triggers Ruger 10/22 replacement trigger set. This is a drop-in replacement for the entire action, so trigger, hammer, springs and magazine release assembly are all new. The magazine release is a lever that wraps around the bottom of the trigger guard all the way to the back. You operate it with a quick flick downward with your middle finger. It’s fast and positive.

How to Replace the Trigger and Magazine Release on the Ruger 10/22

Installation is easy. All you need is a flat head screwdriver and something to punch out the trigger housing pins. I used a Real Avid Gun Tool for the whole operation. In fact, I did this upgrade at the range so I could test before and after performance under identical conditions.

Before you do anything, remove the magazine. Now make double sure that the chamber is empty. Put any nearby ammo elsewhere so there is no risk of inadvertently loading the gun. Now double check once more to make sure the gun is completely unloaded!

Timney Trigger Ruger 10-22-3 Loosen the screw in the bottom of the stock, just in front of the receiver. It will come all the way out. Now you can lift the barrel up and remove the barrel and receiver from the stock.
Timney Trigger Ruger 10-22-5 Completely remove the receiver from the stock. The entire trigger assembly is held in place with two punch pins. Oh, one more thing. See that big hole in the upper right of the receiver in this photo? That’s for a large bolt-stop pin. It likes to slip out, so make sure you don’t lose it.

Leupold’s 300 Blackout Offering: The Mark 4 MR/T 1.5-5x20mm

There’s a reason there are so few 300 Blackout optics on the market. It’s kinda hard to design a single reticle to handle the exceptionally broad range of ballistic performance of that cartridge while keeping the reticle clean and simple.

The turrets are calibrated for 1/2 minute of angle adjustment per click.

The turrets are calibrated for 1/2 minute of angle adjustment per click.

Let’s take a look at exactly what I mean by “broad range of ballistic performance.” For purposes of the trajectories shown in the table below, let’s assume a zero yard zero, and we’ll use two common and “representative” projectiles and “standard” velocities. For the supersonic load, we’ll show the flight path of a Barnes TAC-TX 110 grain bullet. I’ll assume a velocity of 2,500 feet per second. For the subsonic load, we’ll use the classic 220 grain Sierra Matchking and assume a traveling speed of 1,050 feet per second.

The purpose of the “zero yard zero” is to compare the absolute, unadjusted flight paths of the two rounds. Basically, we’re looking at shooting each round exactly parallel to the ground to see how it falls over distance.

300 AAC Blackout Trajectory

As you can see, the brick, I mean subsonic round, falls at about four times the rate of the supersonic. That’s a lot to account for. From an optics perspective, the most feasible plan is to design a reticle for the supersonic round and figure out a couple of realistic hold points for a short range trajectories of the subsonic round.

The Leupold offering is more of a scope tinkerer’s dream. With variable magnification and lots of fine lines in the reticle, you can get it to do whatever you want, out to very long ranges.

Leupold Mark 4 MR/T 1.5-5x20mm

The Leupold Mark 4 is a variable scope with the 300 AAC Blackout specific reticle in the first focal plane. This means that the reticle will grow and shrink as you adjust magnification. At low magnification levels, the inverted horseshoe acts like a red dot, especially with illumination on a high level. At higher magnification levels, you have a finely granulated reticle that provides moving target lead information, range estimation tools and holdover points for supersonic and subsonic loads.

The optic itself is all Leupold. It’s solid and all movements operate like clockwork. Flip up scope caps are provided that mount with rubber friction cups. Unlike others on the market, these stay in place until you want to take them off. The magnification dial is stays in place but is easy to rotate with one hand while keeping a firing grip on the rifle. The windage and elevation dials offer quiet, smooth and positive click adjustments, with each click representing ½ Minute of Angle (MOA) or ½ inch at 100 yards. One nice touch for windage and elevation adjustments is an engraved directional indicator that is visible from the back, telling you which way to twist to the dials to move point of impact up, down, left or right.

Subsonic on the left, supersonic on the right.

Subsonic on the left, supersonic on the right.

Let’s talk about the reticle for a minute. It’s engineered to show hold points for both supersonic and subsonic 300 AAC Blackout loads. Leupold’s approach is to split the reticle horizontally – the right side of center shows supersonic information while the left indicates subsonic. Just in case you forget, there is small and subtle hare engraved in the lower right and a tortoise on the lower left.

The supersonic (right side) markings indicate hold points from 100 to 900 yards with marks at each 100 yard increment. Each horizontal indicator bar is sized to represent an 18 inch wide target at the respective yardage length. For example, if the 400 yard hash mark appears to be the same width as an object you know to be about 18 inches wide, then that object is 400 yards down range. It’s a quick and easy ranging system.

On the subsonic (left) side, there are hash marks from 100 to 400 yards with a line at each 100 yard increment in that range. There is not a 50 yard indicator per se, but between the center dot and bottom of the inverted horseshoe, you can do a quick test to find short range impact points for your chosen subsonic load.

One other reticle feature to note. On either side of the center dot are horizontal lines with hash mark indicators that correspond to hold points to lead targets moving at 5, 10 and 15 miles per hour respectively.

To make the distance hold points work for supersonic and subsonic loads, just zero the optic using supersonic (110 or 125 grain) projectile at 100 yards.

The reticle is illuminated with the inverted horseshoe and center dot lighting up in red. A left side knob offers seven different light levels for low light or daylight conditions. One handy feature is that between each intensity setting on the dial is an “off” position. You don’t have to spin the dial all the way back to zero each time you turn illumination on or off. Just keep is one click from your most commonly used setting, give it a click in either direction and you’re good to go.

Leupold Mark 4 MRT 300 Blackout-5

Closing thoughts

The Leupold optic offers precision at longer range. While the markings are a bit optimistic (400 yards for a subsonic 300 Blackout is quite a lob), I guess that’s no different than the speedometer on your Caddy going up to 160 miles per hour. You can lower magnification and turn on the illumination for quick close range performance, but I think this optic really shines when you are engaging targets out past 100 yards. The glass is crystal clear as you would expect from Leupold, and with the finely graduated reticle you’ll be able to account for distance very precisely.

FNH Makes A Competition Shotgun? The FNH SC-1 Competition Over/Under

As you can see by its appearance, the FNH SC-1 is built for competition.

As you can see by its appearance, the FNH SC-1 is built for competition.

FN. It’s a little confusing if you’ve been around a while. Is FN the same as Browning? What’s Herstal? What’s FNH? Is that different than Fabrique Nationale? Should John Browning win a Nobel Prize? Are Belgian waffles all they’re cracked up to be?

Let’s answer these questions with a simple history review. In 1889 Fabrique Nationale d’Armes de Guerre (FN) was formed for the sole purpose of building 150,000 Mauser rifles for the Belgian Government. A few years later, in 1897, FN’s sales manager traveled to the United States to learn more about bicycle manufacture. We don’t know exactly why, or whether or not he wore those tight biking shorts, but on that trip, biker-student Hart Berg met John Moses Browning, may he rest in peace. That chance encounter kicked off a long and prosperous partnership where FN manufactured many of Browning’s designs including the Browning Auto-5 shotgun, Browning Automatic Rifle and the Hi-Power, which was partly designed by John Browning. John Browning did FN such a solid that when he died of a heart attack in 1926, they stuck his body in the FN board room for visitation. Ewww. I know corporate boardroom meetings are boring, but at least they don’t (usually) include dead people.

Yes, FNH does make a competition shotgun.

Yes, FNH does make a competition shotgun.

Consistent with its military heritage, FN made military rifles, refurbished millions more after the big WWII kerfluffle and then went on to make the FN FAL starting in 1947.

In 1970, Fabrique Nationale d’Armes de Guerre officially changed its name to FN Herstal. Just because. Later in the 1970’s, FN acquired controlling interest in Browning, hence some of that confusion between the companies. Now having an insatiable appetite for American gun companies, FN next bought the U.S. Repeating Arms Company, including the license to manufacture Winchester-brand firearms.

Since that time, FN has manufactured gajillions of military rifles including the M249 Squad Automatic Weapon, M-16, M4/M4A1, MK46, MK48 and M240L machine guns, and the MK19 grenade launcher.

As to the name stuff, FN Herstal begat it’s own parent, The Herstal Group. FN Herstal then begat FN America, who begat FN Manufacturing and FNH USA. And so on and so forth. Got it?

Anyway, it all nets out to this. You might think of FN as a tactical arms company and not one to beget a competition clays shotgun. But remember the brief history lesson: one of FN’s first products was the Browning A5 autoloader shotgun, right? Since that time, FN has produced the FN SLP Standard auto-loading shotgun and the FN P-12 pump action shotgun.

But we’re here to talk about the FN SC-1 Competition shotgun, so let’s get to it.

What is it?

This SC-1 came with five Invector Plus choke tubes.

This SC-1 came with five Invector Plus choke tubes.

The FNH SC-1 Over/Under is, you guessed it, a double-barrel shotgun. It’s designed expressly for clays competition, although there is nothing about it that would discourage other uses. Personally, I wouldn’t hesitate to hunt ducks or close geese with it. Why close geese? As a competition gun, it’s got a 2 ¾ inch chamber. Besides, using 3 or 3 ½-inch shells in a competition gun is kind of silly, and you’d only put yourself at a disadvantage. You certainly don’t need the extra power to break clays and the extra recoil would hurt your second shots, not to mention giving you a tremendous flinch as the competition wears on. Remember, unlike hunting, almost any clay target sport will involve hundreds of shots per day. I don’t know about you, but I’m not really into shooting a hundred or so 3 ½ inch turkey loads in one sitting – I have enough pain in my life.

Also giving a nod to its competition design goals, you’ll find ported barrels and easy to configure chokes. One of the two models also features an adjustable comb.

That’s the quick introduction, now let’s talk about the details.

Four Outstanding AR Optics for Less Than $400

If you splurge on a 1968 Shelby Mustang GT500-KR, you’re not going to fill the crank case with reclaimed Crisco just to save a few bucks. A similar principle applies to optics. Even with AR-15 prices falling faster than BlockBuster Video’s stock price, you’re still probably going to spend north of $600 on a rifle. Don’t cheat yourself by purchasing an optic not qualified for the task. Cheap optics can give you headaches from fogging, poor light transmission and inconsistent adjustment performance. Most frustrating of all are those times you can’t seem to zero your rifle, not matter what, until you find out the reticle in your scope is moving all over the place with recoil. Remember, friends don’t let friends buy those cheap no-name optics you see at gun shows.

Fortunately, you do’t have to spend more than the cost of your rifle on a quality optic. Here are some of my picks for high-quality optics that you can buy for less than $400 – usually a lot less.

Weaver Kaspa-Z Zombie Scope

Before you start with the hate mail over including a Zombie scope, hear me out. Besides, the dead could rise one day. Check out the audience on the Judge Judy Show, and you’ll see what I mean. Anyhow, my contacts at ATK pulled me aside some months ago and said “Do you want to know what one of our best value scopes is?” Being completely supportive of saving money, I asked to hear the story – and got the full pitch, along with an evaluation sample of the Weaver Kaspa-Z Zombie optic. If you’re not into the whole Zombie thing, that’s OK, as the markings on the scope are subtle. Most of the Zombie cosmetics are in the form of optional stickers.

You won't see a lot of Zombie features on this Weaver Kaspa-Z, but you will get a great deal on a general purpose AR optic.

You won’t see a lot of Zombie features on this Weaver Kaspa-Z, but you will get a great deal on a general purpose AR optic.

Here’s why it’s on this list. Built on a 30mm tube, it gathers plenty of light. With a 16 ounce weight, it’s sturdy enough to use as an impact weapon. The 1.5-6x zoom gives you fast, close range capability as well as precision out to the effective range of a 5.56mm round. The real beauty of this particular scope is the Z-Cirt reticle. It’s brilliant. Variable illumination (green of course) makes it easy to see in low light. The posts and hash marks are pre-mapped to known distances with a wide variety of .223 and 5.56 ammunition and serve double duty as range estimation tools. For example, the solid center dot corresponds to a Zombie’s head at 100 yards and the surrounding parentheses indicate the same target size at 100 yards. The first horizontal hash mark indicates 20 inches (average shoulder width) at 400 yards. With all the ranging and ballistic drop compensation functionality, this reticle is still fast at short to intermediate distances.

MSRP is $299.95, but you can find one on the street for about $199.

Nikon M-223 1-4×20 BDC 600

The Nikon M-223 1-4x20 with BDC-600 reticle.

The Nikon M-223 1-4×20 with BDC-600 reticle.

The M-223 is a one-inch tube model with pure 1x to 4x magnification – plenty for realistic .223 / 5.56mm ranges unless your usage is small varmint hunting at the outer limits of ballistic performance. Turrets adjust in ½ MOA increments with a total adjustment range of 100 MOA. Parallax is fixed at 100 yards, so any potential effect is negligible. Eye relief is generous at four inches, which makes placement on an MSR receiver easy – especially with Nikon’s aggressively cantilevered scope mounts or rings. Both one-piece and two-piece cantilever mounting options are available.

The reticle is developed specifically for 55 grain .223 Remington / 5.56mm NATO cartridges and offers hold points from 100 to 600 yards in 50 yard increments. If you shoot heavier projectiles like 77 grain, you’ll have to establish your own hold point distances out past a couple hundred yards.

MSRP is $299.95, but you can find this one for about $280. Check out other options in the Nikon AR family as you can find great deals on fixed power and higher magnification optics.

I Feel the Need for .45 Speed!

The Doubletap Ammunition .450 SMC rounds work from a standard +P rated .45 ACP pistol.

The Doubletap Ammunition .450 SMC rounds work from a standard +P rated .45 ACP pistol.

Sometimes we shooters do things because, well, why not? It’s as good reason as any, right?

At first glance, the .450 SMC cartridge may appear to fall into the “why not” category. When you start to look at specifics and potential use cases, it can make a whole lot of sense.

What’s a .450 SMC you ask?

What if I told you…

  • That you could launch a .451 160 grain projectile at .357 Sig velocities?
  • That you could blast a standard .45 ACP 230 grain bullet 32 percent faster?
  • That you could break 1,300 feet per second with an 185 grain .45 projectile?
  • That you could shoot a 255 grain hard cast bullet from an autoloading handgun?
  • And most importantly, that you could do these things from your existing .45 ACP pistol?

Sound farfetched? Nope. Assuming you have a .45 ACP pistol that’s rated for +P .45 ACP ammunition, you can shoot the .450 SMC to obtain this type of performance, and more. As we speak, Doubletap Ammunition offers five different loadings of .450 SMC.

Whose crazy idea was this?

In late 2000, a company called Triton launched the .450 SMC. Similar to the .45 Super, one primary difference was the use of a small rifle primer, theoretically allowing more brass in the cartridge base for strength. Alas, Triton didn’t last, and the .450 SMC faded away.

Fortunately for us speed freaks, the Godfather of Boom!, Mike McNett, founder of Doubletap ammunition picked up the rights and tooling for the .450 SMC cartridge, and it’s now commercially available again.

What is the .450 SMC?

Note the small rifle primer on the .450 SMC case on the left.

Note the small rifle primer on the .450 SMC case on the left.

Hopefully, it’s obvious that you can’t simply jam more powder into a standard .45 ACP cartridge case to obtain this type of performance. It’s a little more complicated than that, especially considering that the .45 ACP was designed as a low-pressure cartridge running at about 20,000 psi. There’s margin in the design, but you don’t want to go and drive pressure through the roof.

The solution is to use a different case while keeping the same dimensions. The .450 SMC uses a small magnum rifle primer rather than the standard large pistol primer of the .45 ACP. The small rifle magnum provides plenty of ignition power, but the smaller primer pocket means more brass at the cartridge base, hence a stronger case. As a result, Doubletap Ammunition can load the case with five to six thousand more pounds per square inch of pressure than a standard .45 ACP. Also, the stronger case prevents bulging even in a less-than-ideally supported chamber like a Glock 21.

As of now, Doubletap Ammunition is the only provider of .450 SMC. Founder Mike McNett bought the tooling and is now having a good old time loading lots of .450 SMC in various combinations. And I’m having a good old time shooting it.

Beretta’s ARX100: A Quick Tour

 

The Beretta ARX100 is designed to be a Transformer.

The Beretta ARX100 is designed to be a Transformer.

I’ve never watched the Transformers movies, but if my understanding is correct, those flicks were about 1974 AMC Gremlins morphing into deep fried banana splits, thereby earning free admission to the Texas State Fair. Or something along those lines.

Even if I’m a bit off in my understanding of the Transformers plot, you have to admit the idea of effortless transformation on demand is a pretty cool thing. Politicians do it all the time based on poll numbers and density of cameras within 25 yards, so why shouldn’t rifles be able to perform the same feat?

Getting back to the point, since I’m writing this on the Beretta Blog, let’s talk about transformation with respect to the new Beretta ARX100 rifle. Its family heritage is the ARX160 – a 21st century rifle designed for the Italian (and other) militaries and law enforcement organizations. As a result, some mondo engineering has been applied to make this rifle fit not only a wide variety of potential shooters, but also easily adapt to a broad range of requirements. If you haven’t noticed, people come in all shapes and size. Some do most things, including shooting, with the right hands, while others buck the trend and use the left side. Folks are also tall, short and everywhere in between. Don’t even get me started on accessories preferences as it seems no two people on the North American continent can agree on exactly how a rifle should be equipped with optional gear.

Apparently the main design goal of the Beretta ARX100 is to not only accept all these physical and opinion differences, but embrace them. The rifle has been designed to be instantly customizable in many, many ways. Most importantly, all this customization can be done without tools – that’s where the engineering magic comes in.

With all that said, let’s take a quick tour, from back to front. In a future article, we’ll do a deep dive on how the ARX100 operates and shoots. For now, we’ll focus on how it’s put together.

Princeton Tec’s Switch MPLS Hands-Free Light

The Princeton Tec Switch MPLS offers not only a variety of mounting options, but a gooseneck lamp extension so you can point light where you need it.

The Princeton Tec Switch MPLS offers not only a variety of mounting options, but a gooseneck lamp extension so you can point light where you need it.

If you partake in nocturnal activities like fishing, hunting, camping, pub crawling or recreational coal mining, you need a personal light. To keep your hands free for whatever activity you do, you’ll want a light that you can mount  on your hat, clothing or gear.

I’ve been working with the neat little piece of gear to fit this need called the Princeton Tec Switch MPLS. It’s a tactical light, but really more than that. You can use it for a wide range of activities that require “working-level” illumination.

I originally got it to use for general navigation and administrative tasks while at the Crimson Trace Midnight Three Gun event. Last year I made the mistake of using a small white LED lamp equipped on the bill of my hat. It sounded like a great idea at the time, but I quickly learned that people don’t appreciate the use of bright white light as it tends to spoil everyone’s night vision. Red, blue or green LED lights are much more eyeball friendly in dark conditions.

Talking with the folks at Princeton Tec, I explained that I didn’t yet know how I was going to mount the light. Since the light would be used for loading guns and magazines, taping and resetting targets, and finding the next stage in the pitch dark, a handheld light was out of the question. Since I didn’t know how I wanted to mount this new light we decided to try out the Switch MPLS system.

The battery and lamp of the Switch are contained in a housing that’s designed to accommodate multiple mounting attachments. Since the lamp is at the end of a short gooseneck fixture, you can orient the lamp independently from the body and mount of the unit.

The standard Switch MPLS comes with two mounting options:

MOLLE: You can mount the Switch MPLS to a load-bearing vest or backpack.

MICH: If you wear a helmet for a living, this is probably your best mounting option. With firm attachment to the lower side, the light is pre-oriented towards the front and it’s easy to reach for activation and deactivation. A screw clamps the mount firmly to the helmet.

If you need different mounts, just order the MPLS Accessory kit which has these additional mounting adapters:

PICATINNY:  You can mount the Switch MPLS to a compatible rifle rail, or more practically, any range box, case or other accessory with a rail segment. Of course, you can always attach a Picatinny rail segment to just about anything, so use your imagination for solutions such as internal vehicle mounting.

ACH-ARC helmet rail mount.

Four mounting options are available - two included and two more available as options.

Four mounting options are available – two included and two more available as options. In this photo, the light it mounted on the MOLLE adapter.

The Switch MPLS has three light modes: low-intensity color, high-intensity color and 10 lumen white light. You can order models with red, blue, green or infrared light. All models have the white light option included.

One of the things I like most about this piece of gear is the built-in protection against the user whipping on that bright white light inadvertently. To activate the default red light, just press the main button. To make the red light a little brighter, press it twice. If you really want white light, and are sure you’re not going to ruin your, or your buddy’s night vision, you have to hold the button down for a couple of seconds. This, and only this, activates the bright white light, so you have to be very deliberate about wanting the white light activated.

Cool piece of gear – check it out. You can find them at street prices of about $50.

The Making of a Timney Custom Trigger

If you want to get maximum accuracy from your rifle, check out a Timney Trigger upgrade.

If you want to get maximum accuracy from your rifle, check out a Timney Trigger upgrade.

If you’re in the business of eking every last bit of performance out of an already fine-tuned product, you have to have a relentless, bordering on obsessive, sense of attention to detail.

Looking at the factory floor of Timney Triggers, the compulsive behavior quickly becomes apparent. I’m sure you’ve heard the phrase “you could eat off the floor” before. At Timney Triggers, you really can. Well, actually you can’t, because eating off the floor would get it dirty. This place is seriously clean and polished. Even the brass outlet covers and ventilation grates on the factory floor are shined. I suspect even a Marine Corps Drill Instructor would have to begrudgingly express satisfaction.

The folks at Timney wouldn't let me eat off the factory floor as I would have gotten it dirty.

The folks at Timney wouldn’t let me eat off the factory floor as I would have gotten it dirty.

According to Timney Triggers owner John Vehr, this fanatical approach to organization and cleanliness sets the tone for the level of detail that goes into product design, manufacture, testing, shipping and most of all, service. After all, he wants Timney to be known not for products and inventions, but their service. “I want Timney to be the Kleenex of triggers, so people say ‘Check out my Timney’ instead of ‘Check out my trigger.’” The company intends to get to that point my removing internal competition and focusing all efforts externally. “When we no longer compete with each other, but rather outside competitors, it turns out we’re competing with companies that are competing with themselves,” says John. Every one of Timney’s 22 employees signs posters on the wall that detail Timney’s five commitments and Collaborative way. The fact that Timney has virtually no turnover seems to indicate the corporate culture investment is working.

I recently had the pleasure of spending a day touring the (relatively) new Timney manufacturing facility just north of Scottsdale, AZ to see just how Timney trigger parts and assemblies are made. Hint: It’s a fascinating process which is a lot different than you might imagine. Let’s take a look.

Beretta’s ARX100: A Closer Look

As the exterior appearance indicates, the Beretta ARX100 is a complete redesign.

As the exterior appearance indicates, the Beretta ARX100 is a complete redesign.

If you made me describe one thought about the Beretta ARX100, it would be something along the lines of “ambi-flex-trous.”

Yes, you can easily reconfigure this rifle in all sorts of ways, which we’ll discuss in a minute, but the interesting thing is you can do all of it with a bullet. Macho, isn’t it? So far, I have yet to use a single tool of any kind for reconfiguration. Well, there was one exception. I did need a wrench to remove the factory flash hider, but I don’t think that counts as it doesn’t fall into the category of routine maintenance. Don’t tell the Beretta folks I applied wrenches and a bench vise to their loaner rifle, OK?

Let’s take a closer look.

As the ARX100 is a pistol-operated rifle, there's no buffer tube to prevent a folding stock. It shoots in this configuration too.

As the ARX100 is a piston-operated rifle, there’s no buffer tube to prevent a folding stock. It shoots in this configuration too.

The ARX100 looks large and potentially heavy, but it’s not. Judicious use of polymer keeps weight down and unloaded, it tips the scales at just 6.8 pounds. While the stock appears monolithic in design, it breaks into an upper and lower receiver, although the dividing lines are different than the upper and lower components of an AR rifle.

The butt stock is connected to the upper receiver half through use of a hinge, which allows the rifle to operate like a pistol. While the intent is easier transport, shooting with a folded stock feels very Buck Rogers. Since the rifle is piston operated, there’s no buffer tube in the way of pistol operation. The butt stock itself has four different positions to adjust length of pull.

The rifle is covered in web sling attachment points. A rotating swivel is in front of the gas block. The butt has a web sling loop. There are two flat sling loops on each side of the receiver for a total of six.

Rails are also abundant. The entire top surface of the rifle is a continuous rail, so there is no “joint” between receiver rail and forend rail as with an AR rifle. Four-inch rail segments are located up front in the three and nine o’clock positions. There’s a 1 ½ inch rail segment on the bottom in front of the forend cover. If you need to attach a 40mm grenade launcher, remove the lower cover and you’ll find a proprietary rail segment for this purpose. Because military-style rifle. Word is that Beretta may offer a Picatinny adapter at a later date.

It comes with non-standard height sights. They'll get you going, but may not co-witness with your optic.

The ARX100 comes with polymer flip up sights so you can shoot it out of the box. The front sight features a standard, height-adjustable post while the rear has a rotating aperture dial where apertures are calibrated for ranges of 100 to 600 meters. Be aware that these sights are taller than standard AR models, so they may not co-witness as you like. No worries, by pressing a button on each, you can slide them right off the rail if you don’t want them present.

The trigger is all military all the way. It’s big and wide, set in an oversized trigger guard for easy access with gloves. The pull weight leaves something to be desired, measuring 8 1/2 pounds for me, but at least it was smooth and not gritty. The trigger components are held in place by pins, so assuming demand is there, aftermarket companies like Timney should be able to offer replacements.

What a Difference a Trigger Makes

Will adding this to an AR rifle improve accuracy?

Will adding this to an AR rifle improve accuracy?

Gun shop wisdom says a good trigger makes all the difference.

It should be obvious that replacing the trigger doesn’t have any physical impact on a rifle’s accuracy. It’s not like it synchronizes barrel harmonics to the tune of “You’re So Vain” or anything. A trigger doesn’t touch the barrel or impact flight path, yet everyone swears it makes a rifle more accurate.

That’s kind of true. But it doesn’t make the rifle more accurate, it makes it easier for you, the shooter, to get the best accuracy that the rifle is capable of. This is an important distinction.

The reason is that pesky physics thing. When a rifle takes several pounds of pressure to break the shot, and the rifle itself only weighs several pounds, it’s gonna want to move, at least a little bit. A good trigger, with a smooth action and reasonably low pull weight, is going to make it easier for you to break the shot without moving the sight alignment of the rifle. When you’re trying to extract every last fraction of an inch of accuracy, a little bit of unwanted movement means a lot on the target.

According to John Vehr, President of Timney Triggers, “There is only one reason to upgrade a trigger in a firearm – to make you more accurate with the firearm.  A great trigger will allow you to become more accurate by eliminating physical factors like drag, creep and heaviness – Less movement equals better accuracy.  A great trigger will allow the shooter to make the act of pulling the trigger more of a mental decision that a physical decision.  A great trigger is an extension of the mind and should break exactly when the shooter calls for the shot.”

I shot groups with proven accurate handloads before and after the Timney Trigger installation.

Gaining more practical accuracy by using a custom trigger sounds great in theory, but I wanted to put it to the test in a quantifiable way.

I decided to take two rifles of proven quality and accuracy, but with less than optimal triggers, and test their accuracy before and after a trigger upgrade. The folks at Timney Triggers sent me an AR-15 Competition trigger for the test. This trigger, the 3 pound 667 model, is a self-contained unit with drop-in installation.

My thought for the test was simple. Shoot groups of 5 shots each with each rifle with its standard factory trigger. While at the range, swap the trigger for the Timney AR-15 Competition trigger, and reshoot the groups. Same ammunition, same rest, same day, same atmospheric conditions and same shooter. When all was done, I figured on applying some common core math to compare the average group sizes before and after. Then I realized that this article was due in 2014, so I skipped the common core stuff and added, subtracted and averaged the old fashioned way.
