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 5” barrel with a 1:10 twist rate. The FM Products blast diffuser extends past the 5.5” 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. Utilizing a Standard T-style charging handle, you can swap it out for whatever you want. 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
  • 5” 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
  • SB Tactical SBA3 arm brace
  • 1.3" internal diameter handguard
  • 5.5" M-LOK handguard

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. An additional feature with this model is the included SB Tactical SBA3 pistol stabilizing brace. Featuring 5 positions of length adjustability and a nylon strap for securely attaching to different arm sizes. Makes your AR pistol much more usable whether you are shooting one handed, braced against your cheek, or pushing forward against a sling. 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.

Very impressed but with confidence

by -

I have a mpx, Colt 9ar15 and Ruger pcc already. Looking for something that uses Glock magazines. I checked the internet for reviews and bought this. No break in, about 200 rounds of win white box 115 and reloads. One ftf with a win 115. Used magpul, ETS and Glock magazines. I liked the ETS best, but they did not hold open on last shot. Magpul and Glock did hold open. There is no magazine included with the firearm. I was impressed with the fit and finish. Prior to shooting, I did not clean nor lube the gun and it ran very well. Weather was 30 degrees and sunny. I took my aim point PRO off my SCAR and put it on this gun. It was dead on without any adjustments for shooting steel set up for USPSA. I’m very happy with this gun and plan to purchase another. I will loan it out to my niece and sister in law to shoot when they come to visit. A smaller optic would be nice (like a MRO).

Buy this now! Excellent shooter

Soft shooting and super accurate. No FTF through first 200rds. Great purchase so far.

quality product for a low cost.


Very good quality. One thing I didn't like about it is that the blast diffuser prevented screw attachments on the rail (handstop). I ended up replacing the diffuser with a smaller diameter diffuser. No issues with feeding cheap ammo using ets 40 rnd mag, works fine with sig v-crown jhp.
<br>The beefy last round bolt hold open was the selling point when I compared it with other low cost ar9. I wish the side charge was available for the 5" and there were more color options.

Jammomatic with hollow points

Barrel will NOT feed hollow points. If you want a range to the will will only feed FMJ, then this is for you. If you want something that runs, just buy their lower and build your own upper.

Great BANG for the buck!

Purchased this PCC mainly for a bug out pistol, to go with my Glock 19. I’ve tried Glock 15/24/33 mags, the fit/function is spot on. Per FM, I shot 500 rds of steel ammo (break in period). Steel may be good for a break in, but wouldn’t rely on it if my life depended on it. After the steel I shot two types of brass ammo (500 rds, new/reloads), not ONE issue! At first I was afraid of FM products reliability, however after shooting the brass I was happy! I sighted the pistol in at 50 yards (red dot/iron sights), but did most of the shooting at 25 yards. I was impressed with the grouping, for such a short barrel. This is a fun pistol to shoot, nice design, love the brace, no regrets. Problem: some of the charging handle roll pins backed out every time I shot. I contacted FM, they sent me a new one. FM has been great to deal with, great customer service!

This gun shoot amazing. I was using Winchester white box 115gr and using magpul magazine 27rounds no problem.

How did they do it?

Absolutely amazing little gun. I was initially skeptical due to the price-point. But after reading the reviews and watching countless videos, I decided to check it out. I'm glad I did:
<br>- The fit and finish is amazing
<br>- I have 300 flawless rds thru it so far
<br>- It's easily the funnest gun to shoot that I currently own
<br>- The guys at Foxtrot Mike are very responsive (email/ IG)
<br>- I'm SO impressed, that I'm starting to consider some of their offerings in other calibers.

Great Gun


I would buy this product again, it’s just amazing ran 150 rounds through it no problem at all. Customer Service Was Awesome On Both Primary Arms & At Foxtrot Mike Products For Questions On This Gun. ⭐️⭐️⭐️⭐️⭐️
