Details
The Foxtrot Mike MIKE 9 GLOCK Style Complete AR9 Upper Receiver, built exclusively for Primary Arms, pairs a short 7" barrel with a billet upper receiver and an integrated Tri-Lug mount machined directly into the barrel for a smaller, lighter 9mm pistol build.
Features:
- 7" barrel chambered in 9mm, 1:10 twist, non-threaded
- Integrated Tri-Lug mount machined directly into the barrel
- Blowback recoil system
- Billet aluminum upper receiver
- Standard charging handle
- 5.5" M-LOK handguard, 1.3" internal diameter
- Compatible with GLOCK-pattern magazines
Machining the Tri-Lug mount directly into the barrel skips the need for a separately threaded muzzle device, giving you a clean, compact profile with a direct suppressor mounting path. The billet upper receiver allows for more customization of look and feel than a forged equivalent, and this configuration keeps overall length as short as Foxtrot Mike's AR9 lineup gets.
Because this 7" barrel measures under 16", this complete upper is subject to all NFA rules and regulations — know your local laws before purchasing, and use it only in an AR pistol or a legally registered short-barreled rifle.
Note: Foxtrot Mike's lifetime warranty excludes aluminum-cased ammunition, non-OEM Glock magazines (Magpul, OEM Glock, and ETS are recommended), Spikes Tactical Glock-style lowers, and non-Sylvan magwell adapters — using any of these can void coverage.
Foxtrot Mike builds feature-rich, affordable AR-9 and AR-15 uppers backed by a limited lifetime warranty, using premium materials and modern manufacturing processes throughout.

Concerned

Put 32 rounds through it so far, not sure why but the hardgaurd has a wiggle to it and I can rotate the barrel by hand 360° having to take it to a shop to figure out what's wrong.
Really Nice Upper
by Thomas -
I built this on a Tennessee Arms TAC-9 Lower. I am running a 6 ounce buffer and a 308 Spring. It fit tight, as TN Arms make things a little big. I did a little sanding and she fit right on. I had to adjust my ejector to be a little taller, and she functions great. I really like the Tri-Lug for when I silence this in the future.
Absolutely Great Customer Service
by Doug
I purchased one of these and love it. Best 9mm upper on the market in my opinion. But what I was really stunned by was Foxtrot Mike's outstanding customer service. I was experiencing issues not being able to dismantle the BCG completely by removing the firing pin. Via email they diagnosed the issue and decided to send me a completely new and updated generation FM9 BCG, free of charge.
Couldn't be happier with their products and their support. Highly recommend!
FOXTROT MIKE PRODUCTS 7" ULTRA LIGHT 9MM TRI-LUG COMPLETE UPPER
by Jimmie -
Purchased this with the FoxTrot Mike pcc pistol lower. Slapped the two together and fired hundreds of rounds with absolutely no malfunctions whatsoever. For the price and the performance I don’t think I could have found a better deal for the price. Extremely impressed with this product. Very fun to shoot.
Great PCC
by SJL
I’ve owned this upper for around 2 years. Paired it with a FM lower from Brownell’s. It’s a blast to shoot. Purchased a YHM R9 suppressor to run with it. Very soft shooting. Much less recoil than 5.56.
This is the best
by Carlbo
This trailer gets cut into the barrel and not in addition over thread. I’ve had this now for three years and it is hands down the best way to connect a suppressor. It’s spring loaded with pressure so it doesn’t come loose and you can put it on in under three seconds don’t hesitate by this
Excellent quality pcc upper!
by Brian
Put mine on a FM lower with an SB brace. Had to buy them separately as nobody offers a complete with this upper. Just passed the 1K round mark & it’s run flawlessly, not a single hiccup. Waiting for SilencerShop to get some more YHM R9’s; already have my tri-lug adapter & it works perfectly with the included mount.
Of the several FM guns I’ve handled all have been well built & reliable. Recoil is also very soft compared to other direct blowback AR-9’s I’ve shot. My 13 year old daughter loves this gun & says it’s her favorite to shoot out of all the firearms we have.
Good purchase

Will this work for fostech echo sport trigger?
by Martin C. III
Will this work with a binary. Fostech echo sport which requires an m16 engagement. Is the bolt cut to function like an m16 bolt
Great upper
by Papa Ogre
This thing runs perfectly on my PSA lower and shoots better than I expected. 5 rds in about 1.5” at 50’, supported (elbows on bench, standing.) with a cheap red dot.
Plenty good for a PDW 👍🏻
