The Brownells AR-15 hammer drop block is a drop-in Delrin component designed to provide users with an accurate sense of trigger movement and pull weight, eliminating the need to use their thumb. This shock-absorbing block prevents the hammer from striking the magazine well wall, thereby reducing the risk of damage to the receiver and hammers. It is compatible with the magazine well of an AR-15 when the upper receiver is open or removed.
