The MPR platform’s superior accuracy, versatility and shootability can be attributed to many features, including a Ruger muzzle brake, Elite 452 two-stage trigger, free-float handguard with Magpul M-LOK accessory attachment slots and Magpul furniture.
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.
Engineered with a high-strength superalloy bolt and tapered lug geometry, the .450 Bushmaster MPR is built to withstand the strength of a cartridge that delivers twice the energy of 5.56 NATO. The upper receiver features a large window for easy ejection and is covered by a standard dust cover. Mil-Spec forgings are CNC-machined, anodized and finished with Ruger’s Elite 452 two-stage trigger, Magpul MOE grip and MOE SL stock.
The rifle ships with a 5-round metal box magazine.
