The build uses skewer hardware:
2x Slug screws 4-40
to attach the back of the grip
For the first version you need:
1x 10-32 long screw
to attach the back nub.
I also made a version that uses a dovetail instead of the 10-32 screw, but it is untested as of now.
Both versions use the silly collet to attach to a barrel. If there is enough interest I may consider the dowel version.
Edit: 7/18/25 Found a mistake in the Dovetail grip, file has been fixed. Sorry for the inconvenience
The author remixed this model.
This is a original grip made to replace the one on the foam fork (Barrel version)
