AR 45 80% Lower Receivers
WHAT IS AN AR-45?
The AR-45 is exactly what it sounds like: an AR style rifle chambered to shoot in 45 ACP. Rather than use a 45 ACP handgun, many like to opt for the AR45 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.
AR45’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.
IT’S TIME FOR YOUR AR-45 BUILD
We have the best 80% billets on the market and that goes for every caliber. Our 80% AR-45 lower receiver billets are meticulously CNC machined to the highest quality standards out of 6061 aluminum which are also used in the aerospace industry.
Remember, these 80% lower receivers are not completed parts which require you to do the last 20% of the work. That’s why 80 lowers are not considered firearms, and why why we’re able to ship them straight to your door!
