The Foxtrot Mike Products FM-9 Complete 9x19mm Upper Receiver is built from the ground up to provide outstanding reliability and accuracy with a host of top tier features. The traditional M4 charging handle has been replaced with an ambidextrous, non-reciprocating forward charging handle. The monolithic style has been achieved with a proprietary interlock between the upper and handguard. The slim-line free float handguard is M-LOK compatible for your favorite lights, grips, and tactical accessories. The 9.25” barrel is made from durable 4150 chrome moly vanadium steel and has an FM Products forward blast diffuser attached, bringing the overall length to 10.5”. This AR-9 upper receiver group mounts to virtually any Glock compatible 9mm lower receiver including Angstadt Arms, New Frontier Armory, Palmetto State Armory, and Quarter Circle 10, so you can build your dream AR style pistol or carbine.

AR style 9mm carbines are some of the most fun to shoot at the range. With a properly tuned recoil spring and buffer, the 9mm blowback system results in low recoil so it can be enjoyed by shooters of all types. Because 9mm ammo is generally affordable, 9mm pistol caliber carbines make for long days at the range plinking or training. There is also a wide range of ammunition types available from steel cased to high power defensive rounds, so you can use it as an effective home defense solution.

Feature rich, high-quality, and affordable, Foxtrot Mike Products offer cutting edge solutions utilizing the highest quality materials and manufacturing processes available.


Manufacturers Note: For optimal reliability, FM Products does not recommend using aluminum case ammo in their uppers or complete firearms.

Amazing product and quality.

This upper was impressive from the moment I unboxed it. The quality is outstanding and it is light, but feels high quality at the same time...super solid. I took it to the range and put about 500 rounds through it. 100 brass, 300 steel, and 100 hollow points. Not a single issue. I am more than thrilled with this purchase. I would recommend this to anyone looking for a quality upper for their AR-9 build. The side charing feature is also amazing. If you ever have to clear a malfunction (double feed, stuck case, etc), the side charging feature will allow you to not have to take the rifle off your shoulder to clear it, unlike the rear position of the AR-15 charging handle...super thought out design. I am impressed with this thing.

WOW! Way too much fun!! You need one

This thing is amazing! Fit & finish are excellent. Mated it to an FM-9 lower and went straight to the range. After a quick boresight and 5 minutes shooting I had it zeroed (20 yards). The holes were touching - i's a tack driver! It's very comfortable to shoot. I had so much fun with this. The side charging handle makes a lot of intuitive sense once you get used to it.
<br> Additionally, I had a few questions about this and the FM lower. The service from Primary and FM both were fantastic. I can't imagine how to improve on it? Regarding the lower, last round bolt hold open worked perfectly every time. Standard Glock mags drop free easily, but the 33 rounders were a bit sticky. A little sandpaper and plastic polish fixed it though. I built this for competition - can't wait. I highly recommend this complete upper!! The only things I added that are not FM: SBA3 brace, Rise Armament HP trigger and Holosun 510C sight.

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'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.
