Foxtrot Mike Products MIKE 9 Complete AR9 Upper Receiver - 9mm - 7"

The Foxtrot Mike MIKE 9 Complete AR9 Upper Receiver at 7" pairs a lightweight 41V50 barrel with a Mil-Spec rear charging handle and a free-float M-LOK handguard, giving you a compact, traditional-layout 9mm pistol caliber carbine build.

Features:

• 7" lightweight 41V50 steel barrel, Melonite coating, 1:10 twist
• Chambered in 9mm, threaded 1/2x28
• 5.75" M-LOK free-float handguard
• Mil-Spec rear charging handle
• Billet aluminum upper receiver, Type III hardcoat anodized
• Micro blast diffuser installed

Unlike Foxtrot Mike's front-charging MIKE 9 variants, this build keeps the familiar rear-charging layout AR-15 shooters already know, so there's no adjustment period switching between platforms. The 1/2x28 threaded muzzle accepts standard suppressors and muzzle devices beyond the included micro blast diffuser, giving you room to upgrade later.

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.

The billet aluminum receiver and Type III hardcoat anodizing give this upper a rugged exterior finish, and the 1/2x28 threaded muzzle leaves room to swap in a different muzzle device or suppressor down the road.

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.
