Manufacturers Note: FM Products does not support the following items, using these may void the lifetime warranty associated with our uppers;
1) 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.
2) FM Products does not support import magazines besides OEM Glock magazines. We recommend Magpul, OEM Glock and ETS magazines only.
3) 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.
4) 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.

Good Upper, Wrong Answer re: Threading
Love the upper, but I’m out $$$ for buying a 1/2x36 muzzle brake for it because the answer to that question was misleading. When I emailed FM, they said they ship it with either a 1/2x28 OR a 1/2x36, so check the threads yourself before ordering another muzzle device.
USI gave it a shot, worked fine.
This build started with a 80% lower and standard Anderson lower parts kit. This 5" upper was just the assembly to use. I mated the pieces last weekend and put a mag thru it for a quick test. No issues at all. Now if suppressors would just come down to reality on pricing without a Government hit list?
My new favorite
This 9mm ar upper is awesome i love it way cheaper than shootin 223/556 but just as much fun. Plus it looks cool as ****
USGreat way to convert to 9mm
Easy swap. Fit perfectly to my Aero Precision lower. The Endo mags work great and hold the bolt open. No complaints here.
United StatesTac Driver & great customer service
This fm9 is a tack driver. Have run all kinds of ammo, very accurate for a 5 inch barrell. I paired mine with a budget Red Dot and everything has went great. I sent it in one time because when I received the upper it had the old school with a flip up dust cover,& my cover would not stay shut so I sent it in and they put a whole new upper and the whole new hand drill because it was a newer model they gave me an upgrade because of my trouble. Like I said great customer service.
