Replacement for the Bottom plate of the EPM 1-S short M4 airsoft mag 170 rounds.
Two versions available, one with inlay to customize the color, the other one is just a replacement cap you can print in any color as one piece.
inlay is a little smaller and separate piece because of print orientation.
inlay in the photo was printed on a PEI pattern build-plate. Adjust your buildplate type accordingly.
