CMMG carbine buffer assembly works correctly. Inside weights dont rattle. Phosphate steel body wont show wear. Wish a spare detent had been included for the price. Otherwise function is what you need for any carbine cycling.
standard carbine buffer assembly from CMMG, comes with the buffer and rubber bumper. weight balance is correct for a carbine gas system. install is direct into a mil spec tube. cheap and reliable
