Roughcut Masterkey Backplate

Back cover for masterkey, to cover up the big hole that you sawed off
This is after doing the slamfire mod, pictures show where you need to saw off for this part to work.

Hardware needed: 2 screws. Like those that you won't be using after sawing off 30% of the blaster
