What is a Pistol Caliber Carbine (PCC)?
A Pistol Caliber Carbine (PCC) is an AR-style firearm chambered in a handgun cartridge such as 9mm, 10mm Auto, 40SW, or .45 ACP instead of a traditional rifle cartridge. PCCs are popular for recreational shooting, competition, and training because they combine familiar AR controls with manageable recoil, modular customization, and caliber options to suit a variety of shooting preferences.
