Ruger® AR-556® MPR 5.56 NATO/.223 Remington Semi-automatic Rifle

It's the wildly popular AR-556® you know and love, but with a few key enhancements that make it easier to shoot and a lot easier to love. Like the original, the AR-556 MPR is built around a forged 7075-T6 aluminum receiver and cold hammer-forged 4140 chrome moly barrel, delivering rock-solid durability and performance.

However, unlike the original, the AR-556 MPR comes standard with a compact, lightweight B5 Bravo collapsible stock and B5 Type 23 pistol grip. The original heat shield handguard has also been replaced with a much better "Lite" 13.5" free-float handguard with M-LOK attachment slots. And perhaps most importantly, the original single-stage trigger has been replaced with the outstanding Elite-452TM 2-stage trigger, offering a crisp, consistent 4.5-lb. trigger pull and 30% faster lock time than standard triggers. Yet despite all these improvements, the AR-556 MPR is STILL highly affordable. That makes it a home run in our book.

  • Cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning
  • The Ruger Elite 452 AR-Trigger is a 2-stage trigger that offers a smooth, crisp, 4.5 pound trigger pull
  • Full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a 30% faster lock time over standard MSR triggers
  • B5 Bravo collapsible stock is lightweight and compact
  • B5 Type 23 pistol grip features an increased vertical angle compared to the A2, and has an extended tang
  • "Lite" 13.5" free-float handguard has M-LOK slots at 3:00, 6:00, and 9:00
  • Bolt is machined from 9310 alloy steel and is shot peened and pressure (proof) tested to ensure strength, structural integrity and durability
  • Chrome-plated bolt carrier inside diameter and chrome-plated gas key inside diameter provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing
  • Ruger® muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement
  • Barrel is threaded 1/2x28 for standard muzzle accessories
  • 1:8" twist rate stabilizes bullets from 35 to 77 grains
  • Rifle-length gas system provides smoother operation and reduces felt recoil.
  • Includes (1) 30-rd. PMAG®
