Ruger has introduced three configurations of its new Pistol Caliber Carbine (PC Carbine) Chassis model. New features on the standard model of the PC Carbine include a glass-filled polymer chassis system; six-position, telescoping, Magpul MOE buttstock; flared magwell for improved magazine reloading capabilities; ergonomic pistol grip with extended trigger reach; and a factory-installed, barrel-mounted Picatinny rail. Additionally, two 10-round state compliant models are available. One with an adjustable stock and threaded barrel, and the other with a fixed stock and non-threaded barrel.
The new, glass-filled polymer chassis system allows for the use of standard AR pistol grips and collapsible buttstocks. The adjustable ghost ring rear sight of the original PC Carbine has been replaced with a factory-installed, barrel-mounted Picatinny rail, which allows for the forward mounting of optics. These new models utilize a CNC-machined, hard-coat anodized aluminum handguard with Magpul M-LOK accessory attachment slots on all four sides for easy mounting of M-LOK-compatible accessories.
These models also maintain several hallmark features of the original PC Carbine, including: an easily interchangeable magazine well system that allows the rifle to accept common Ruger and newer Glock magazines; dead blow action with a custom tungsten weight that shortens bolt travel and reduces felt recoil and muzzle rise; reversible magazine release and charging handle to accommodate right- or left-handed shooters; a simple takedown mechanism to allow for quick separation of the barrel/fore-end assembly from the action; durable heat-treated, chrome-moly steel bolt; cold hammer-forged chrome-moly steel barrel with ultra-precise rifling; and in some models, a 1/2" x 28 threaded barrel.
The PC Carbine Chassis model ships with the SR-Series magazine well installed and an additional magazine well that accepts newer Glock magazines. A 9 mm Luger Ruger American Pistol magazine well is available separately at ShopRuger.com.
