Ruger's AR-556 MPR is made from 7075-T6 hard-coat anodized aluminum forgings, shot-peened and proof-tested 9310 steel bolt, and 8620 steel bolt carrier. It features a lower receiver that is fitted with Magpul MOE grip and MOE SL collapsible buttstock on a Mil-Spec buffer tube. Its handguard is free-floated for accuracy and the slim, 15" length provides enhanced ergonomics. The handguard uses 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. 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. The threaded, cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning.
