Moriarti AR-47 7.62x39 16" Upper – 1:10 Twist, 15" M-LOK Free Float, Carbine Gas

16" AR-47 Upper with 15" M-LOK: Specs

Upgrade your AR-15 with the stopping power of the AR-47 7.62x39 16" Upper Assembly, built for reliability, durability, and superior accuracy. Compatible with all standard mil-spec AR-15 lower receivers, this upper delivers the AK-caliber performance in a streamlined AR platform.

The heart of this upper is a 16" 4150 CMV barrel, phosphate-coated and button-rifled for long service life and excellent accuracy. It features a 1:10 twist rate, ideal for stabilizing a variety of 7.62x39 loads. A triport muzzle brake tames recoil and muzzle rise, while 5/8x24 threading allows future suppressor or brake customization.

A 15” M-LOK free float handguard gives you generous mounting space for accessories, optics, and foregrips while reducing barrel deflection for better accuracy. The low-profile .750 gas block and carbine-length gas system ensure consistent cycling, whether suppressed or unsuppressed.

The forged 7075-T6 A3 flat-top receiver is anodized to government specifications and comes complete with forward assist and dust cover.

Note: Handguard design may vary slightly based on stock availability. All configurations meet Moriarti’s premium quality standards.

FAQ

What do I need to run a 7.62x39 upper?

A standard mil-spec AR-15 lower, a 7.62x39 bolt carrier group with the larger 7.62x39 bolt face, and AR-15 pattern 7.62x39 magazines. A standard 5.56 bolt and magazines will not work.

Why might I get light primer strikes?

Many 7.62x39 loads use hard military-style primers. A heavier hammer spring or an enhanced firing pin usually solves it; see our guide linked below.

Is a bolt carrier group included?

No. Add a 7.62x39 bolt carrier group; it is available as an add-on on this page.
