Butt pad for AR-15 or M16 full size rifles. Fit the butt of SP1 or AR-15 A2 version by attaching to the butt on the small screws that hold the butt plate on. Black rubber pad adds 1/2" length and helps prevent slips.
This will not allow for use of the cleaning kit hole found on some of the later model of the AR-15 type rifles .
It is for the early model of AR-15 with no hole in the end of the buttstock .
