Smith & Wesson M&P 15-22 Load Assist Button
Sliding magazine load assist buttons for the Smith & Wesson M&P 15-22 magazine.
This is especially designed for the 10 round pinned magazines from S&W that cannot be disassembled to insert your own follower load assist button. It will work on any 15-22 magazine; however, it is not designed to be removed through the existing hole at the bottom of regular non-pinned magazines.
I am currently selling these on eBay, but wanted to make the model available for people to 3D print on their own.
