AR-47 7.62x39 18" Upper Assembly / 1:10 Twist / Mid-Length Gas / 15" M-LOK Free Float Rail – Moriarti Arms
For shooters looking to push the ballistic limits of the 7.62x39 cartridge, the Moriarti AR-47 18" Upper Assembly offers increased velocity, flatter trajectory, and enhanced accuracy—perfect for hunting, distance shooting, or tactical builds.
This upper features a premium 18” 4150 CMV barrel with 1:10 twist, nitride coated for longevity and corrosion resistance. The mid-length gas system provides smoother recoil impulse and improved cycling over traditional carbine systems. Threaded 5/8x24 and finished with a triport muzzle brake, this setup delivers performance and control.
The 15" M-LOK free float rail gives you ample space for bipods, lights, grips, or optics while preserving accuracy by preventing barrel deflection. The forged 7075-T6 A3 upper receiver includes forward assist and dust cover, precision-machined and hardcoat anodized for durability.
Note: Handguard may vary slightly in appearance depending on stock. Quality and fitment remain consistent.
