Built exclusively for Primary Arms, this Foxtrot Mike Products side charging 9mm AR pistol is packed full of features like a billet upper and lower receiver set compatible with Glock magazines and a blast diffuser that extends the 7” barrel past the M-LOK handguard. The forward mounted charging handle allows you to stay on target during magazine changes and charge your pistol much faster than a traditional T-handle. It is non-reciprocating, so you can keep your support arm fully extended on the rail without fear of causing a malfunction. Because of the simple blowback design, it is extremely rugged and reliable with full power ammunition. The Fm9 also features an M-LOK compatible free float handguard with picatinny top rail that is flush mounted to the flat top upper receiver. Housing the recoil buffer and spring is a smooth pistol length buffer tube. If you are looking for a Glock compatible 9mm AR-15 pistol, you can’t go wrong with FM Products.

Outstanding AR9 for the money !!!

by -

Received my FM9 last week and added some extra accessories to it. Went to the range and ran 250 rounds thru it with no problems what so ever. This AR pistol is completely solid and the bolt lock back feature is a nice touch. The bonus is the side charging handle. This is a extremely well thought out design inside and out. The bolt is just pure precision as well as the trigger. Cleaning the pistol is a breeze compared to other AR's. I highly recommend this FM9 not only for the price, but all the great features it has to offer.

UPDATE 5 Stars

UPDATE!!!! Most BUIS do clear the thin charging handle... I was very mistaken and want to make sure everyone knows BUIS do work with the front charging handle... FIVE STARS!!!!

Almost perfect...

by -

Great fit and finish, overall I'm pleased with my purchase... The only reason I didn't give it 5 stars is because of the inability to mount BUIS on it due to the forward charging handle getting in the way. I supposed I could mount a sight behind the charging handle, but that is less than ideal and looks cheesy.

Exactly what I was looking for

After six months of looking at 9mm AR's , I pulled the trigger (pun intended) on the FM 7" and bought it on sale. Primary Arms Is awesome to deal with anyway but this pistol is way beyond your average 9mm AR. Ran 100 rounds Of cheap reloads through 3 different brand mags without a single problem. I am more than happy with it. The last round bolt hold open works perfectly. If you don't have this option , you wish you did. With a lifetime warranty and customer service with Foxtrot Mike ( Paul ) being as good as it gets, puts you way ahead of the game in pistol cartridge AR's.

Well worth the money!

I have been nothing but pleased with my purchase. With 1000 rounds through it using the Fostech Echo AR II trigger, this thing can stand up to anything. It's even gotten me a couple first place finishes in my steel matches. This little AR pistol paired with the companies top notch customer service will make any shooter happy they bought it.

One word “awesome!”

by -

This thing is awesome! I haven’t had one hiccup with it. I’ve ran about 200rds through it and it hasn’t skipped a beat. If you’re wanting a 9mm AR without breaking the bank, get this one. I just wish they made a 10mm. Great job Foxtrot Mike and Primary’s Arms.

100% happy customer here

Great deal for the price. The bolt hold open feature works like a champ. It ran flawlessly with the 20rds I tested on it when I got it. I threw a cheap red dot sight on it and was hitting my 12x20inch plate without zeroing it. If they made a 10mm, I’d ditch the other brand one I bought and had issues with the first 13 rounds. Buy this without hesitation, or the one with the normal charging handle. I’d prefer the other charging handle to this one but it wasn’t an option when I bought it. The charging handle feels kind of cheap, but works. It’s awkward locking the bolt back with the current charging handle but not a deal breaker. Maybe they could move the location of the current charging handle back a little bit to not get in the way with front sights being added. Either way, 5 stars and highly recommended for anyone wanted an AR in 9mm. I am 100% happy with my purchase even with the small things I mentioned.

I’m super happy, great price and great quality

by -

It’s works as it should. The bolt locks open as it should. It fed my ammo through it with no issues. I’m super happy about it. The side charging handle is a little rough/stiff but it’ll get better. At 30yds without zeroing my red dot, it was 14 out of 14 on a 12x20 plate.

Great gun but read if you have a fostech echo

by -

This is a fantastic firearm. Running a sig Romeo 5 on it and no issues so far. Runs like a dream and feels nice. Only issue you'll encounter is if you're using a fostech echo AR II. I was told it would work fine with the bolt provided but it won't clear when assembling the upper and lower unless you slide a thin blade in and push the trigger lock forward out of the way of the rear of the bolt.
