Foxtrot Mike Products is at it again with another 9mm AR pistol exclusively built for Primary Arms. For those wanting an even smaller and lighter pistol, this build features a short 7” barrel with a 1:10 twist rate. The FM Products blast diffuser extends past the 8.75” M-LOK handguard and directs all the excess gas and concussion of your shots forward instead of the sides, making this much more enjoyable to shoot at indoor ranges. The upper and lower receivers are machined from billet aluminum allowing for a greater degree of customizability for look and function. The magazine well and upper receiver feed ramps have been machined for use with Glock magazines, yet it is still compatible with standard AR-15 parts like a trigger, pistol grip, and safety selector. The integrated magazine release is much larger and easier to reach than the Mil-Spec alternative allowing for quicker magazine changes. This FM-9 features the popular forward mounted side charging handle that can be swapped to either side. Foxtrot Mike is building some of the most popular AR-9s on the market and Primary Arms is proud to offer them directly to you.

  • Ambidextrous charging handle
  • 7” barrel chambered in 9mm
  • Billet upper and lower receiver
  • Glock compatible magazine well, receiver, and bolt
  • Enlarged magazine release
  • Blow back recoil mechanism

This blowback 9mm pistol comes with a smooth pistol length buffer tube and buffer/recoil spring combination tuned to reliably cycle a wide variety of ammunition. The heavy 9mm bolt also helps to increase dwell time and reduce bolt bounce ensuring safe and smooth feeling action. Feature rich, high-quality, and affordable, Foxtrot Mike Products offer cutting edge solutions utilizing the highest quality materials and manufacturing processes available.

Great Home Defense Gun

by -

Love this gun! Functions great and really easy to shoot. Very happy purchasing this for home defense for my wife and daughter while I am at work.

would buy again

Haven't shot it yet but this thing is pretty sick. It feels real good except the finger groove on the grip is placed wrong for my smaller hands, my middle finger sits on top of it. Also this is the first gun I've ever bought that didn't include at least one mag... good thing I already have some extra Glock mags.

Awesome gun!

I bought this gun for home defense, as it has several advantages: short barrel, minimal muzzle flash and report, affordable ammo (for training) purposes, the rounds & mags are interchangeable with my carry pistol, front charging, and high-quality LRBHO. It's amazingly fun to shoot, even my wife (who really doesn't like shooting) had fun. I'm glad I went with the 7" barrel, as there is very little usable rail space. You can't mount anything on top of where the charging handle rides, as the picattiny mount will block the charging handle. You also can't mount around the flash can, as there is insufficient clearance for the M-LOK bolts. Still, I was able to mount an angled grip on the bottom and I used a 45-degree offset rail to mount a flashlight from the top (set about halfway back). This gun is sweet, especially for the price!

Good Value

Fast shipping. Came as separate upper/lower. Hinge pin was missed when lower was assembled. Contacted FM and was sent a return label and apologies. Once the lower was back, I installed MBUS sights. Had an issue with the side charging handle hitting the mounted sight preventing the gun from being charged. I had to remove material from the bottom of the MBUS sight to provide enough clearance to be able to charge. FM recommended lubing up the gun really good and using 600 rounds of steel case Tula to break it in. Day 1: I shot around 400 rds through the gun without issue. I discovered I do not like the short charge handle as it is not easy for me to operator with one finger. I contacted FM and ordered a Para- trooper style change handle for the gun. Day 2: I completed the break in and tested some Critical Defense hollow points and some HST's. Functioned flawlessly. In closing - I had zero issues with function. The LRBHO worked flawlessly every time. I only used Glock mags. Recommended!

Lots of fun for the money.

Shot mine for the first time today. Ran just fine from the first round. Used Glock and ETS mags and 124 grain magtech ammo. Fun, easy to handle, and seems to run great. Come with no magazine, but you likely have a Glock mag or two around already. Mount your red dot sight and have at it.

Best bang for your buck!

All the features that you want for a price you can afford. This thing has ran 100% so far using ETS g18 mags. Accurate little 9mm as well. This is the best bang for you buck for a PCC "pistol".

Buy it

I purchased this pistol during the Black Friday sale. I have over 2000 rounds through it. It runs with Magpul and Glock mags. I have oiled it a few times but have not yet cleaned it. I highly recommend this gun. Very reliable, fun.
<br>I let 2 of my friends shoot it. They both bought one.

Great pistol
