Ruger's PC Carbine rifle features interchangeable magazine wells for use of common Ruger and Glock magazines. Its Dead blow action features a custom tungsten dead blow weight that shortens bolt travel and reduces felt recoil and muzzle rise. The cold hammer-forged, chrome-moly steel barrel is also heavy contoured with fluting. The durable, glass-filled nylon synthetic stock features sling swivel studs, soft rubber buttpad with spacers, and the grip has a proprietary texture for enhanced control. Its CNC-milled aerospace-grade 7075-T6 aluminum billet receiver includes an integrated Picatinny rail and adjustable ghost ring rear and blade front sights. The PC Carbine also has a light, crisp trigger pull and ambidextrous controls. This model has 1/2"-28 threads along with an included thread protector.
