Ruger's PC Carbine semi-auto rifle is a well-balanced, fast-handling weapon that delivers rapid fire. The carbine is adaptable, with interchangeable magazine wells, for use with either GLOCK pistol magazines or Ruger pistol magazines. The receiver is CNC-milled from a 7075-T6 aluminum billet and type-III hard-coat anodized for maximum durability; and, the receiver comes with an integrated Picatinny rail. The durable, glass-filled nylon synthetic stock has a forward-mounted accessory rail, proprietary texturing on the grip surfaces, and a rubber buttpad with spacers to adjust length of pull (includes three 1/2" spacers). The PC Carbine takes down quickly for storage or transport, by pushing a recessed lever and twisting the barreled fore-end from the receiver and pulling them apart. The heavy-contour barrel features fluting for faster heat dispersion. The rear aperture sight adjusts for windage and elevation, and the front post is protected by wings on both sides. The dead blow action features a multipiece bolt assembly that reduces felt recoil and muzzle rise for enhanced fire control.
