I’ve seen magazine ads for the Mossberg FLEX system for sometime now, but have not had the opportunity to kick the tires, so to speak, until now.

The Mossberg FLEX system allows you to swap stocks, grips and butt pads quickly and easily.

If you’re not familiar with the Mossberg FLEX, the idea is a system of interchangeable parts, like stocks, grips, buttpads and forends, that allow you to quickly and easily reconfigure a rifle or shotgun. There are plenty of good reasons you might want to do this.

  • Seasonal clothing changes. If your shotgun or rifle fits you perfectly in the cold months when you wear heavy clothing, it might be a bit long in the stock during the summer t-shirt months.
  • You may want to share the same rifle or shotgun with another person who requires a different length of pull than you – a child for instance?
  • Maybe you want to use and home defense. Why not mount a solid stock for hunting outings and a collapsible for home defense use?
Butt pads are a piece of cake to swap. A button on the bottom of the stock releases one, so you can add a different size.

Before I saw the system I had hesitations about the about how solid this the mounts would be. After all, the stock is the focal point for heavy recoil forces in shotguns and rifles. At the recent Professional Outdoor Media Conference (POMA) I had the opportunity to swap some stocks and shoot.

I found the locking system to be rock solid and here’s why. Mossberg uses zinc fixtures on both male and female sides of the locking mechanism between the stock and receiver. The locking mechanism is similar and appearance and function to AR style barrel extension and bolt carrier the way the two pieces locked together. A semicircular lever lifts out of the stock itself and twists 90° to release the mechanism. A quick bump with your hand and the two halves come apart. It’s a tight fit and I could detect no “play” at all between the receiver and stock.

You can also swap the butt pad for different sizes with a simple button release on the bottom of the stock. The butt pads are designed to snap in place and are available in small, medium and large sizes. Mossberg also offers different sizes of stocks blanks so you actually have two ways to customize. First you choose the stock you want, then select the desired butt pad. Couldn’t be easier.

Mossberg makes the FLEX system for , 7.62mm and 5.56mm MVP bolt action magazine fed rifles, 20 gauge shotguns and now FLEX-22 rifles.

Cool stuff.
