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
  • Blast diffuser muzzle device
  • Mil-Spec AR-15 lower parts kit
  • 1.3" internal diameter handguard
  • 8.75" M-LOK handguard
  • SBA3 Pistol Stabilizing Arm Brace

This blowback 9mm pistol comes with a SBA3 Pistol Stabilizing Arm Brace 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.

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

Great pistol

by -

Love this bad boy! Light weight and really fun to shoot! Needs some oil Right away, but it runs like a champ!

Buy it

by -

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.

Best bang for your buck!

by -

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".

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.

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!

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!

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.

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.

Beyond worth the Money.


Ridiculously happy I purchased this instead of building the one I'd planned. Perfect fit with zero wobble in the receivers and rail. LRBHO. Runs Glock and ETS mags without any issues. 7" is just long enough for an angled Foregrip. Ran fine out of the box, bone dry, with lube it is pure Bliss. You can spent the same amount of money on just a stripped receiver set... But this is way better bang for your buck.

Accurate and reliable!


Great pistol! I purchased the SAAE trigger at a discounted price and a Magpul MOE slim grip. I have put 300 rounds down range with no issues. My wife and daughter are able to hit the 10 ring consistently at 25 yards. I also added the Sig Romeo5 red dot and Olight with pressure pad. Very accurate and love shooting this pistol.

Rig ran flawless

Rig ran flawless out of the box! Very pleased and rig is a blast to shoot!



I was skeptical because of the price, but wow. If you are wanting a small pcc, this is one you can not go wrong with.

Best value


You can't beat the customer service combo of Primary Arms & Foxtrot Mike. This rig is a blast and is perfect for home defense or just fun. Plenty of options for a light and red dot and you've got the best little package for the money.

Won't disappoint


This firearm is fun, accurate, and reliable. Very happy I got this. I've put 2000 rounds through it and its been flawless. Wish I could upload video to show it off

Killer AR-9


I have had my Primary Arms exclusive side charging FM9 for a month or so now. I couldn’t be anymore pleased! This thing runs like a champ! Right off the bat I was completely surprised in the quality in the upper and lower receiver. The machine work is fantastic and the fit and tolerance is perfect. I’ve only run about 500rds through it but not a single problem. I’ve used Amend2, ETS, Magpul and factory Glock mags. It runs them all flawlessly. Installed a set of FAB defense buis and the charging handle clears with only minor rubbing. Very minimal sanding and it clears perfect. For what you get this is an amazing deal at this price. Stop think about it and just buy one

High recommend


This pistol shoots great. Very little recoil. You loose a few inches on the rail due to the charging handle being in the front of the pistol so a longer barrel might be necessary if you want iron sights. I ran Steel and brass ammo and used Glock mags and CTS without a problem!



Over a thousand rounds of all different brands and grains ammunition not a single issue.It likes to run wet.very accurate

Great Gun Foxtrot


Great PCC

Doesn't feel cheap


I am very pleased with this purchase. If you bought something similar to this right now, you better be looking at paying at least twice this price (if not more). It feels good in my hands and the material doesn't feel cheap. If you are on the fence with buying this I would highly recommend you do it sooner rather than later because a) you will not regret it and b) we have people in office that try and chip away at our right to protect ourselves.

Everything I wanted in a 9mm AR pistol


Great price and loaded with awesome features. Mine has the new gen 2 forward charging handle that is angled up so tilting the gun to the left for a good grip also gives a great view of the chamber. Perfect for competition and the unload and show clear command. The oversize mag release button can't be missed. The muzzle device did seem to lessen blast. I bought Magpul mags as the Foxtrot Mike site suggested and they worked flawlessly and drop clear even when fully loaded. I am very impressed with the overall quality, fit and finish and the accuracy is excellent. The trigger is too heavy for competition but just right for a home defense gun. I could not be happier with my purchase.

Foxtrot Mike


Gun is smooth and fun to shoot. Definitely needs oil right away.
