The Ruger® AR-556 MPR Semi-Auto Rifle with Proof Research® Carbon-Fiber-Wrapped Barrel features a Proof Research 18" carbon-fiber-wrapped barrel, bringing serious weight reduction, precision accuracy, and good looks to this stellar platform. A rifle-length gas system reduces recoil for comfortable shooting on this Ruger chambered in .223 Wylde, which allows 5.56 NATO and .223 Remington ammunition. This precision-shooting AR-15 is fitted with a Magpul PRS Lite stock, which offers length-of-pull adjustments with secure lockup and comb height adjustments. The Magpul K2 pistol grip has excellent ergonomics. The Ruger Elite 452 AR-Trigger is a 2-stage trigger, offering a 4.5 lb. clean and crisp trigger pull. A 15" free-floated handguard features M-LOK® attachment slots for a world of accessories. A radial-ported Ruger muzzle brake greatly reduces felt recoil by decreasing muzzle rise. This excellent, accurate rifle also comes with one 30-round Magpul PMAG®.
