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.

Excellent...but
by Grant
Was able to put this upper through it's paces. It is flat-out reliable and gave excellent accuracy at 50 and even 100yds. I only used Fed hardball ammo and was getting 2-1/2" 5-shot groups consistently from the bags with a Romeo dot sight. My only complaint comes when using a 2-point sling (rt hand shooter) and you do a fast mag-change drill. The shooter must break position to re-charge the 1st rd from the new mag. If the charge handle were on the right side...a rt hand shooter could stay slung up.
Ran perfectly right out of the box

You can stop looking, this is the upper you need. Paired with a FM AR9 lower, this is a fantastic set up. Ran perfect from the very first round. I could not be happier. Great innovations as well. Everything you could want. I thought I would be sacrificing with the lower price but that was not the case. This upper is worth way more than they are charging.
