This grip plug allows the user to securely store backup batteries on their rifle inside the Magpul MVG verticle grip.

This design should be printed in TPU for best results follow the recommended settings as infill and walls settings will change the fit and function of the part.

Conceptually, this part should create a water resistant seal at the bottom of the grip further protecting your batteries, I suggest weathersealing the screw holes of the MVG for best protection against the elements.
