7.62x39 AR-15 Uppers – Complete AR-47 Upper Assemblies

How to Choose a 7.62x39 AR-15 Upper
Shop AR-47 7.62x39 uppers combining the familiar AR-platform configuration with the proven 7.62x39 cartridge. Available in Micro, pistol and rifle-length configurations, these complete upper assemblies offer options for compact setups, range use and general-purpose builds. Explore Moriarti 7.62x39 AR uppers in multiple barrel lengths and styles, and pair your upper with the appropriate 7.62x39 bolt, magazines and compatible AR-15 lower receiver.
Does a 7.62x39 AR upper use a standard 5.56 AR-15 bolt?
No. A 7.62x39 AR upper requires a 7.62x39-compatible bolt because the cartridge has a different case-head diameter than 5.56 NATO. Reliable configurations should also use magazines specifically designed to feed 7.62x39 ammunition in an AR-platform lower.
How to choose a 7.62x39 AR-15 upper
- 5"–7.5" uppers: Micro ARP and Krinkov-style AR pistol builds. 7.62x39 keeps good energy from short barrels and makes a compact, hard-hitting package.
- 10.5" uppers: a balance of handling and velocity, with fake cans, cone brakes and quad rail options.
- 16"–18" uppers: full rifle length with carbine or mid-length gas for hunting and range use, including stainless fluted and Cerakote builds.
Our 7.62x39 barrels use the standard 1:10 twist and 5/8x24 muzzle threads, in 4150 CMV with nitride, phosphate or Parkerized finish, or 416R stainless.
7.62x39 upper FAQ
What do I need to run a 7.62x39 upper on my AR-15?
A standard mil-spec AR-15 lower, a 7.62x39 bolt carrier group with the larger bolt face, and AR-15 pattern 7.62x39 magazines. A standard 5.56 bolt and magazines will not work.
Why does my AR-47 get light primer strikes?
Many 7.62x39 loads use hard military-style primers. A heavier hammer spring or enhanced firing pin usually fixes it; read light primer strikes on your new AR-47.
