HOW TO INSTALL: Adjust your M4 adjustable stock to the longest setting. The circular pin at the bottom of the lever you pull to adjust the stock is pulled out farther than the lever allows (you will most likely need a pair of pliers to get ahold of the circular pin and pull it downward). While pulling the pin downward, silmultaneously move the butt of the stock away from the reciever and it will come off. After it is off there is a small ALLEN screw on the bottom of the stock pole which will release the cap at the end of the pole. Once that cap is removed there is a screw which needs to be taken out from within the pole. Once you unscrew the screw in the stock pole simply slide off the pole and change the adapters.
