This is a vertical pistol grip and horizontal fore grip all in one designed to fit a standard M4 length lower rail. The current file works fine however my printer cannot handle the entire piece at once. I am currently working on breaking it into 3 parts so that you can hook them together with a couple screws and print much easier. I cut the hex holes for the screws to fit a 6/32 machine screw I picked up from the local hardware store. If you want a different screw size, feel free to message me.
The "Sample Test Piece" will let you print a small piece to make sure it fits your rail before printing the entire grip. As the sample picture shows, it is designed to fit a standard set of picatinny rails.

I am an engineer by day and a part time 3D designer enthusiast by night. I mainly do table top minis, terrain, etc. but I have also done many other projects such as gun accessories and a few mech designs.
I'm flexible and easy to work with. So, if you don't like something you see then feel free to shoot me a message and I'll be happy to make any changes so that my design fit your needs :)
