AR 9 80% Lower Receivers

WHAT IS AN AR-9?

The AR-9 is exactly what it sounds like: an AR style rifle chambered to shoot in 9mm. Rather than use a 9mm handgun, many like to opt for the AR9 to have a pistol caliber carbine. A Pistol Caliber Carbine, or “PCC,” is a short, lightweight rifle chambered in any caliber typically found in handguns i.e. 9mm or .45 ACP.

AR9’s in particular have a lot of benefits as they have very low recoil, almost non-existent muzzle flash, and are extremely user friendly for beginners. For more experienced shooters they make a great choice for personal defense with their maneuverability.
