Built exclusively for Primary Arms (go to PA website). The FM Products blast diffuser extends past the 5.5” M-LOK handguard and directs all the excess gas and concussion of your shots forward instead of the sides, making this much more enjoyable to shoot at indoor ranges. The upper and lower receivers are machined from billet aluminum allowing for a greater degree of customizability for look and function. The magazine well and upper receiver feed ramps have been machined for use with Glock magazines, yet it is still compatible with standard AR-15 parts like a trigger, pistol grip, and safety selector. The integrated magazine release is much larger and easier to reach than the Mil-Spec alternative allowing for quicker magazine changes. Utilizing a Standard T-style charging handle, you can swap it out for whatever you want, however, the FM9 comes with a Radian Raptor, so why would you ever want to. Foxtrot Mike is building some of the most popular AR-9s on the market and Primary Arms is proud to offer them directly to you.
