  • Lower receiver is fitted with Magpul® MOE® grip and MOE SL® collapsible buttstock on a Mil-Spec buffer tube.

  • Handguard is free-floated for accuracy and the slim, 15″ length provides enhanced ergonomics.

  • To support the large case head of .450 Bushmaster ammunition, the .450 Bushmaster bolt is engineered with tapered lugs and machined from a high-strength superalloy.

  • The Ruger® Elite 452® AR-Trigger is a two-stage trigger that offers a smooth, crisp, 4.5 pound trigger pull. It features a full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a faster lock time for improved accuracy.

  • Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00 and 9:00 positions with additional slots on the angled faces near the muzzle.

  • Ruger® muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The threaded barrel allows for standard muzzle accessories to be installed.

  • Cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise 5R rifling and black nitrided finish provides exceptional accuracy, longevity and easy cleaning. The heavy barrel profile and 1:16″ twist rate maximizes accuracy with bullets ranging from 170 to 260 grains.

  • Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver includes a forward assist, dust cover and brass deflector, and is Type III hard coat anodized for maximum durability.

  • Bolt carrier and gas key have chrome-plated inside diameters to provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing.

  • Carbine-length gas system provides the most reliable function with .450 Bushmaster ammunition.

  • Also includes: one, 5-round metal magazine.
