The Ruger® AR-556® MPR Semi-Auto Rifle operates with direct-impingement and a rifle-length gas system. The lower receiver comes equipped with a Magpul® MOE® pistol grip and a MOE SL™ 6-position, collapsible buttstock on a Mil-Spec buffer tube. Upper and lower receivers are CNC-machined from 7075-T6 aluminum forgings. A 15'' free-float, M-LOK® handguard features accessory attachment slots at 3:00, 6:00 and 9:00 positions, and a continuous Picatinny rail interface with the flat-top, railed, upper receiver.
The upper receiver features a forward assist, dust cover, and brass deflector. A Ruger® Elite 452® 2-stage, AR-Trigger offers a smooth, crisp break at approximately 4.5 lbs. The bolt carrier and gas key have chrome-plated inside diameters to provide exceptional resistance to hot gases; and the gas key is securely staked to prevent loosening during extensive fire.
