Build an AR: Choosing and Installing the Barrel

Barrel fluting doesn't just look cool, it has practical benefits too. This LWRC barrel is 20% lighter and cools faster.

The beautiful thing about building your own rifle is that you can be really, really picky about what components you choose. It’s your rifle, and you’re building it for your specific purposes so you can optimize each and every part according to your intended use of the finished product. While numerous components and the assembly […]

AR Operations: Direct Impingement vs. Piston Operated

Imagine the bolt (below) inside of the bolt carrier (above) and you can see how the gas flow works.

All AR-type rifles have plenty of gas; they just deal with it differently. Eugene Stoner had plenty of gas. So much so that he designed his AR-15 semi-automatic rifle to work entirely on gas flow. The method of operation was called direct impingement. Well, people refer to it as direct impingement, but it’s really a […]

Celebrate Diversity! The World of AR-platform Calibers

The AR platform can be adapted to dozens of different calibers, like this Rock River Arms LAR-6.8 chambered in 6.8 Remington SPC.

In these troubled times where everyone wants to stir up trouble and hate over our differences in appearance, I want it to go on record that I don’t just tolerate diversity, I embrace it. In my safe right this moment, I have AR-type rifles chambered in .223/5.56mm, 6.8 SPC, 300 Blackout, and .308 Winchester. Of […]

Gun Review: The FN-15 DMR Designated Marksman Rifle

The FN-15 DMR comes out of the box with a variety of features for longer range accurate shooting, like an 18-inch barrel.

Recently I got my hot little hands on one of the new FN America rifles for 2015. This one is the FN-15 DMR or Designated Marksman Rifle. It’s designed to shoot accurately. More specifically, it’s designed to shoot longer and heavier projectiles accurately. Does it? Let’s find out. What makes a DMR a DMR? If […]

5 Great AR Rifles for Less Than $1,000

The AR rifles on this list are solid base models ready for gear and customization.

The great Obama AR-15 Sale of 2013 is over, sort of. Yes, fears about political shenanigans like green tip 5.56mm ammo bans and other nonsensical moves are driving sales, but we’ve moved on from the time when there were no AR-rifles of any type available on the shelves. In fact, as the market has chilled […]

A Close Look at CMMG’s 300 Blackout Mk4 Pistol

OK, so this one was temporarily souped up. No worries, there's a factory configuration photo here too.

I think the 300 AAC Blackout caliber was really made for short barrels. Don’t get me wrong, I have a 300 Blackout AR-type rifle with a 16-inch barrel and love it. I just think the flexibility of the caliber really shines in short and compact configurations. When shooting subsonic, velocity loss resulting from a shorter […]

ATI’s New TactLite AR Stock Eliminates the Shake

The new ATI TactLite AR stocks. The standard model is on the left and adjustable comb model on the right.

You might have noticed that most adjustable butt stocks for AR-type rifles shake just a little. Worse yet, the farther you move that adjustable stock back, the more the shake. We’ve probably learned just to accept it, kind of like that “sproing” sound that many ARs used to make when fired. While the movement of […]

Advantage Arms Offers Forward Charging Handle Conversion Kit for AR-type Rifles

Advantage Arms Forward Charging Handle

This one caught my eye from a distance. Imagine a tubular frame firmly mounted on the upper of an AR-type rifle. The rear interfaces with the standard AR-type charging handle, while the tubes extend to a new charging handle alongside the forward hand guard. Like other designs such as the MP-5, your AR-type rifle can […]
