NOTE: This upper assembly has a barrel less than 16” in length. These uppers are intended for use in AR-15 pistols or legal short-barreled rifles. Other configurations may violate Federal law.

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: 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.

I love my FM-9 Upper

by

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.

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 am very pleased with FM-Products. Very nice quality products, and plus Primary Arms has really fast shipping. You won’t be disappointed!!

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

by -

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.

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.

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.

Best 9mm upper Ive seen

by

Perfect length for your ar9 pistol! Works flawlessly with my aao 80% lower. Side charging handle is plastic but after emailing the company they allowed me to buy the metal folding handle that should be in tomorrow. Absolutely love this thing though. Great product, fantastic company. 10/10 would recommend.

Sooooo much fun!

Ordered this upper to mate up to their lower. It put a SBA3 and a .308 rifle buffer spring like their assembled ones. Other than an alignment issue with the barrel that does not reflect the quality or craftsmanship of F.M. I contacted Primary and they got me squared away super quick and in time for a unit morale shoot! After this was all together it ran without issue. None at all. This thing is so FUN! You need one of these. I went with the 9” so I wasn’t putting my hand so close to the muzzle and my MBUS sights fit.

You have got to be kidding.....

Its rare to find deals these days. Cheap doesn't mean reliable usually and expensive doesn't mean quality. I was searching for a 9mm AR upper for a while before I ran into these guys. I even waited a year since purchasing before I wrote this review to really put it through its paces and see how it does. So many times people get a item and write a review the same week having never shot it based entirely on its looks. This upper is astounding. Its utter reliable having never done anything but feed what I threw at it. Its accurate, its pretty and most of all its downright fun. I put mine on a billet PSA lower with a brace, and a sig romeo5 red dot. Its my cheapest built AR in my safe but it runs like my best. If you are looking for a 9mm AR that won't break the bank and can be not just a range toy but a real go to gun this is it.

Great Upper!

by

Awesome! Got it super quick. Married it up with a Foxtrot Mike 9mm lower. Functioning flawlessly with ETS and Glock mags!

Runs like a top!

by

Finally found one of these in stock. Mated it with a PSA lower and it runs like a top out of the box. The only downside is that I was surprised at how thin the metal of the hand guard is. I can flex it with finger pressure at the front.
