Foxtrot Mike Products is at it again with another 9mm AR pistol exclusively built for Primary Arms. For those wanting an even smaller and lighter pistol, this build features a short 5" barrel with a 1:10 twist rate. 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. 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.

Manufacturers Note: FM Products does not support the following items, using these may void the lifetime warranty associated with our uppers;
- FM Products does not support Aluminum Cased ammo. Blow backs have a much higher pressure spike in the chamber than a handgun. Using Aluminum cased ammo in a blow back PCC is dangerous and will void the lifetime warranty of an FM Products Upper Receiver.
- FM Products does not support import magazines besides OEM Glock magazines. We recommend Magpul, OEM Glock and ETS magazines only.
- FM Products does not support Spikes Glock style lower receivers. The LRBHO requires consumers to modify the FM Products upper, to make egress for the Spikes LRBHO. The FM Products upper is cut to the Colt spec, therefore we have no plans to deviate from that. Modifying your FM Products Upper to accommodate a Spikes Tactical Glock style lower will void the lifetime warranty on our PCC Uppers.
- We only recommend Sylvan magwell adapters, as they require no modifications or adjustments to work properly. FM Products does not support Stern Magwell Adapters as they require regular adjustments to work properly.
