An AR-47 BCG (bolt carrier group) is a vital component for AR-15 style rifles chambered in 7.62×39, also known as AR-47s. It includes the bolt, carrier, gas key, firing pin, cam pin, and retaining pin, all designed to handle the unique dimensions and pressures of the 7.62×39 cartridge. The AR-47 BCG works with AR-15 upper receivers, 7.62×39 barrels, charging handles, and lower receivers, ensuring reliable cycling, chambering, extraction, and firing in AR-47 platform builds.
