For 2019, Ruger has introduced a new model of its popular AR-556 MPR chambered for the straight-walled .450 Bushmaster cartridge. The bolt is machined from high-strength superalloy, and engineered with tapered lugs to support the large case head of .450 Bushmaster ammo.
The all-new .350 Legend is designed specifically for hunters to deliver massive downrange energy transfer with improved penetration from a modern straight-walled cartridge, and boasts more muzzle energy than the .30-30 Win., .300 BLK and .223 Rem.
