The AR-556 MPR has proven to be an excellent hunting platform, and the .350 Legend chambering expands that role. The nitrided 16.38″ barrel is capped with a 1/2″-28 radial port muzzle brake. The rifle’s appeal is enhanced by the combination of a Ruger® Elite 452® AR-Trigger, Magpul® furniture and a 15″ free-float handguard. Magpul M-LOK® accessory attachment slots make the addition of a sling or bipod easy. With less recoil, and weighing almost a pound less than its .450 Bushmaster counterpart, the MPR chambered in .350 Legend is a fantastic hunting option.
