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.
5) Some aftermarket Tri-Lug muzzle devices may not be compatible with this product. For any questions regarding parts and compatibility, please contact us at info@primaryarms.com and we will get back to you as soon as possible.

Excellent quality pcc upper!
by Brian
Put mine on a FM lower with an SB brace. Had to buy them separately as nobody offers a complete with this upper. Just passed the 1K round mark & it’s run flawlessly, not a single hiccup. Waiting for SilencerShop to get some more YHM R9’s; already have my tri-lug adapter & it works perfectly with the included mount.
Of the several FM guns I’ve handled all have been well built & reliable. Recoil is also very soft compared to other direct blowback AR-9’s I’ve shot. My 13 year old daughter loves this gun & says it’s her favorite to shoot out of all the firearms we have.
This is the best
by Carlbo
This trailer gets cut into the barrel and not in addition over thread. I’ve had this now for three years and it is hands down the best way to connect a suppressor. It’s spring loaded with pressure so it doesn’t come loose and you can put it on in under three seconds don’t hesitate by this
Great PCC
by SJL
I’ve owned this upper for around 2 years. Paired it with a FM lower from Brownell’s. It’s a blast to shoot. Purchased a YHM R9 suppressor to run with it. Very soft shooting. Much less recoil than 5.56.
FOXTROT MIKE PRODUCTS 7" ULTRA LIGHT 9MM TRI-LUG COMPLETE UPPER
by Jimmie -
Purchased this with the FoxTrot Mike pcc pistol lower. Slapped the two together and fired hundreds of rounds with absolutely no malfunctions whatsoever. For the price and the performance I don’t think I could have found a better deal for the price. Extremely impressed with this product. Very fun to shoot.
Absolutely Great Customer Service
by Doug
I purchased one of these and love it. Best 9mm upper on the market in my opinion. But what I was really stunned by was Foxtrot Mike's outstanding customer service. I was experiencing issues not being able to dismantle the BCG completely by removing the firing pin. Via email they diagnosed the issue and decided to send me a completely new and updated generation FM9 BCG, free of charge.
Couldn't be happier with their products and their support. Highly recommend!
Really Nice Upper
by Thomas -
I built this on a Tennessee Arms TAC-9 Lower. I am running a 6 ounce buffer and a 308 Spring. It fit tight, as TN Arms make things a little big. I did a little sanding and she fit right on. I had to adjust my ejector to be a little taller, and she functions great. I really like the Tri-Lug for when I silence this in the future.
Concerned
by Joseph -
Put 32 rounds through it so far, not sure why but the hardgaurd has a wiggle to it and I can rotate the barrel by hand 360° having to take it to a shop to figure out what's wrong.
