What is an AR47 lower?

An AR47 lower is a standard Mil-Spec AR-15 lower receiver used to build a rifle chambered in 7.62x39 when paired with a compatible AR47 or 7.62x39 upper assembly. The lower receiver houses the fire control components, buffer system, and stock, while the upper determines the firearm's caliber and operating characteristics.
