Ratings & Reviews
The best 9 mm AR pistol upper on the market, period.

After a lot of research, I found FM uppers to be highly regarded for fit, finish, and accuracy. I built up a pistol with this upper on a PSA AR-15 lower with a Stein Defense Glock mag conversion kit. This, (now an AR9 pistol) is one of my favorite guns. It is extremely accurate, standing unsupported @ 50' 1" groups all day long, feeding any and all 115 and 124 gr. ammo as fast as I can pull the trigger with zero stoppages. I only have 2 33 round and 2 17 round mags which I run through in about 10 minutes, so stock up on ammo if you get one of these.

I am very pleased with FM-Products. Very nice quality products, and plus Primary Arms has really fast shipping. You won’t be disappointed!!
Don't Hesitate, Buy it.
I've done about 3 days worth of research on 9mm uppers and what company I should run with. Honestly Foxtrot Mike Has exceeded my expectations as far as quality and price are concerned. So one thing I do want to point out where people had concern is the side charging handle being made out of polymer. I can tell you with confidence this is not an issue and that they made this change specifically because it would not affect performance and it would make it mildly cheaper for the customer. Hope this helps and have fun!
I love my FM-9 Upper
I love mine! So compact, we got one of the new billet lowers, and ours runs great. The quality is amazing, read all the reviews and the customer service is great. Cant go wrong, accurate too.
