The Ruger PC Carbine rifle features an interchangeable magazine well for use of common Ruger and Glock magazines; a custom tungsten dead blow weight that shortens bolt travel and reduces felt recoil and muzzle rise; heavy contoured fluted cold hammer-forged chrome-moly steel barrel; glass-filled nylon synthetic stock features sling swivel studs; grip has a proprietary texture for enhanced control; 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. Includes SR-Series Pistol and Security-9 magazine well installed and an additional magazine well accepting Glock compatible magazines. *Note- Older Glock magazines that feature only one magazine latch slot may still be used with the PC Carbine but the magazine release button must remain on the left side of the rifle as shipped from the factory as the magazine will not properly lock into the magazine well.
