The Ruger AR-556 M-LOK rifle is a box magazine fed, autoloading, ar style rifle perfect for new and experienced shooters alike. The AR-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 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.


  • Rifle-length gas system for smoother operation and reduced felt recoil
  • Free floating handguard
  • Crisp trigger pull
