Does anybody know how to remove it to change it? I picked up an aftermarket one and it didn't come with any directions. 
Thanks,

to change the mag release button you have to press the buttton fully in, while holding it in you will see a bar come out on the other side of the rifle , with the rife upeside down you can turn the bar towards tou, (counter colckwise) and the bar will unscrew from the mag release button, slowley release the old mag button ( because there is a spring behind it) line up the new button , press in the betton and rethread the bar (colckwise) hope this helps

The mag release for the 15-22 won't work on the m&p 15 sport, you have to get. A release for a regular colt style ar
The M&P-15 Sport is a 5.56 version. I have it as well as the 15-22.Is the "M&P Sport" something different?
The M&P15-22 magazine catch is standard M16/AR15 parts.
Heck, you can insert an M&P15-22 magazine into the M16 or M4 carbine. If the bolt is open. Not vv due to the M&P15-22 magazine well being deliberately smaller than the M16.
