Details

The Magpul® MOE® grip and MOE SL® collapsible buttstock on a Mil-Spec buffer tube ensure ergonomic handling and adjustability. A free-floated, slim 381mm handguard provides modern accessory mounting points via the Magpul® M-LOK® system.

The .450 Bushmaster bolt is reinforced with tapered lugs and machined from high-strength superalloy for reliable performance. The Ruger® Elite 452® AR-Trigger delivers a two-stage, 4.5-pound crisp trigger pull with fast lock time and consistent ignition.

A Ruger® radial-port muzzle brake reduces recoil and muzzle movement, and the cold hammer-forged 4140 chrome-moly steel barrel with 5R rifling ensures long-lasting precision.

The Type III hard-coat anodized upper receiver features a forward assist, dust cover and brass deflector. Internally, the bolt carrier and gas key are chrome-plated to resist heat and fouling.

Includes: one 5-round metal magazine.
