Replaces the trigger guard on an AR. An adjustable screw helps removing the extra pre-travel and post-travel of the trigger. This makes a mil-spec trigger really feel like a high-end drop-in trigger that will increase your shooting performance, allows for more accuracy, less margin for trigger movement error, and faster speed.
