Modern AR Platform Design

The Harrier represents Ruger’s modern evolution of the AR platform, offering enhanced rigidity, improved recoil management, and a free-float handguard system for increased accuracy potential. The tensioned receiver fit system minimizes movement between upper and lower receivers for a tighter overall build.

Free-Float M-LOK Handguard

The slim-profile free-float handguard features M-LOK attachment slots at the 3, 6, and 9 o’clock positions, along with intermediate forward mounting slots. This allows users to easily attach lights, grips, bipods, and accessories without affecting barrel harmonics.

Magpul Ergonomics

Equipped with a Magpul MOE-K2 grip and Magpul DT carbine stock, the Harrier delivers improved comfort, control, and shooting stability. These components are widely trusted for their durability and ergonomic performance in AR-platform rifles.

Threaded Barrel & Muzzle Device

The 16.1-inch barrel is threaded 1/2x28 and comes fitted with an A2 flash hider, providing compatibility for a wide range of muzzle devices and suppressor-ready configurations where legally permitted.

Enhanced Bolt Carrier System

The nitrided bolt and bolt carrier group feature a staked gas key for improved durability and reliability under sustained use, making the Harrier suitable for both recreational and defensive applications.
