The Ruger AR-556 MPR rifle is a gas impingement driven, box magazine fed, autoloading rifle. The mechanism utilizes the gas from the firing of the round to drive the bolt carrier rearward and rotate a bolt that locks into the barrel. The Ruger AR 15 556 rifle can be field stripped without the use of tools and breaks down into basic subassemblies. The safety, located above the trigger on the left side of the lower receiver, blocks the trigger and permits the bolt carrier to be cycled with the safety in the on or “SAFE” position. A bolt catch mechanism is provided for convenience in holding the bolt open for loading and inspection. The firing pin is retracted mechanically as the bolt starts to unlock and the rifle will fire only when the bolt is locked.
The Ruger AR556 MPR features a handguard that is free-floated for accuracy and the slim, 15″ length provides enhanced ergonomics. Magpul M-LOK accessory attachment slots along the 3:00, 6:00 and 9:00 positions of the handguard, along with additional slots on the angled faces near the muzzle allow any combination of accessories to be attached to the rifle.
The Ruger Elite 452 AR-Trigger is a two-stage trigger that offers a smooth, crisp, 4.5 pound trigger pull. It features a full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a faster lock time for improved accuracy. The Ruger muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The threaded barrel allows for standard muzzle accessories to be installed.
