Ruger AR-556 MPR Does it All

Ruger FirearmsU.S.A.-(Ammoland.com)- Sturm, Ruger & Company, Inc. (NYSE: RGR) is proud to announce the new AR-556 Multi-Purpose Rifle (“MPR”). This custom-built modern sporting rifle features an 18” nitrided alloy barrel with rifle-length gas system, Ruger’s 15” free-float handguard compatible with M-LOK accessories, the Ruger Elite 452 AR-Trigger and ergonomic Magpul furniture. The perfect rifle for a variety of uses, the AR-556 MPR is capable and versatile.

“We are very excited to add this model to our modern sporting rifle lineup,” said Ruger President and CEO Chris Killoy. “Our talented team of engineers worked carefully to develop the ideal custom package for the AR-556 platform that does it all, right out of the box. From plinking to competition shooting, the MPR is the perfect rifle for just about anything.”

The MPR’s cold-hammer forged 18” alloy barrel with 5R rifling is salt bath nitrided for corrosion resistance and durability. The barrel is contoured to minimize weight without sacrificing rigidity, leaving a 0.75” journal for the low-profile gas block. The soft-shooting, rifle-length gas system paired with a Ruger muzzle brake provides smoother operation and softens recoil to keep every shot on target.

Ruger’s 15” free-float handguard is light, stiff and versatile, with Magpul M-LOK accessory attachment slots along the 3:00, 6:00 and 9:00 positions. Additional slots on the angled surfaces near the muzzle are perfect for mounting a light, laser or QD sling cup. Compared to a typical quad-rail forend, the 1.50” diameter handguard makes the MPR’s forend slim and controllable. M-LOK-compatible Picatinny rail sections can be easily added. The integral Picatinny rail at the 12:00 position is tightly controlled to the most current STANAG 4649 specification.

The crisp 4.5 pound trigger pull of the Elite 452 two-stage trigger is a great addition to the MPR. The lower receiver is fitted with Magpul’s MOE grip and Mil-Spec MOE SL buttstock, making the rifle easy to handle, shoulder and shoot. The Mil-Spec compatible lower and upper receivers are CNC-machined from forgings and hard coat anodized. The MPR comes complete with dust cover, brass deflector and forward assist.
