U.S.A. –-(Ammoland.com)- Sturm, Ruger & Company, Inc. (NYSE: RGR) is excited to announce the new AR-556 Multi-Purpose Rifle (“MPR”) chambered in .450 Bushmaster. This new offering is ideal for hunting Midwestern whitetail deer and big pigs and target shooting at heavy steel.

The MPR platform offers superior accuracy, versatility and shootability by incorporating a Ruger muzzle brake, Elite 452 two-stage trigger, free-float handguard with Magpul M-LOK accessory attachment slots and Magpul furniture. This new rifle combines innovative engineering, modern materials and precision CNC-machining to make a superior rugged, reliable, semi-auto rifle chambered for the .450 Bushmaster cartridge.

Accuracy and velocity are maximized with a nitrided, 18-5/8” cold hammer-forged barrel and the 11/16”-24 radial port muzzle brake to soften recoil. A carbine-length gas system with 0.875” gas block ensures reliable function and fits under the 15” free-float handguard. The Magpul M-LOK accessory attachment slots around the handguard make attaching a sling and bipod easy. The handguard’s smooth profile situates easily on shooting sticks or a backpack for a steady shot.
