An AR-15 bolt carrier group (BCG) without hammer is a critical assembly for AR-15 rifles, responsible for cycling, chambering, extraction, and firing. It includes the bolt, carrier, gas key, firing pin, cam pin, and retaining pin, but does not include the hammer from the fire control group. The AR-15 BCG without hammer works with AR-15 upper receivers, barrels (such as .223/5.56, 300 Blackout), charging handles, and lower receivers. The hammer’s installed separately in the lower receiver as part of the fire control group.
