Basepad, MBX - For MBX Magazines

The MBX basepad is a replacement part for MBX magazines. One size fits all calibers and length magazines. The basepad is made out of billet aluminum material that has been hard anodized in either black, red, blue, or gray. The pin toward the front of the pad facilitates tool-less removal – simply slip the basepad onto the bottom of the tube and then push up the pin.

Although this basepad can be used on an STI magazine, this is not  something we recommend.
