Features an 18" PROOF^® Research carbon fiber wrapped barrel that is both attractive and significantly lighter than standard barrels, while still offering excellent accuracy and repeatability.

Lower receiver is fitted with Magpul^® PRS Lite^® stock that balances the rifle and has secure length of pull and comb height adjustments for the best fit. Magpul MOE-K2^® grip provides ergonomic access to trigger and safety controls.

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

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.

Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver includes a forward assist, dust cover and brass deflector.

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.
