This is a collection of parts to create pump grips of various sizes. These files are meant to be used with my Retaliator and Magnus shotgun parts:

These pump grip parts will allow you you make much shorter (or longer!) pump grips than I previously made available. Mix and match parts to find the ideal pump grip size for your project!
The pump grip front and rear parts have pockets for M4 nuts. You'll need to find the appropriate length of M4 bolt for the thickness of your priming bar material.
