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.

Ratings & Reviews
Impressed with this upper
Received this upper and immediately put it on my Rock River lower with Hahn adapter running Colt SMG mags. Mounted a Sig Romeo5. Sighted it in using 3 shot groups at 50 yards. 4 groups in had it dead on, all 3 holes touching. Was impressed with the quality of the components for the price. Last round bolt hold open worked great. We'll be using it for PCC competitions.
A Very Fine Upper
Put one on a friend's lower and it functions perfectly with several factory hardball loads. No hiccups whatsoever. Bench tested 5-shot groups ran 2 to 2-1/2" at 50 yards using the ball ammo. Plenty good for any scenario in an urban environment. Fire standing position w/o sling on a 1/2 size steel echo target at 100yds and dinged it every single time. The only drawback was recharging the weapon while slung up with a 2 point sling. You must break position to pull the charge lever back. Had it been on the right side, no problem.
