Picatinny Handstop

thingiverse

A Simple Handstop for my Caliburn pump foregrip mounts via Picatinny rail. This versatile design might also be suitable for airsoft or real firearms, but I have only tested it on a Caliburn 'nerf' blaster, taking into account temperature and recoil considerations. This handstop helps keep your hand from slipping when using a traditional or thumb-over-bore hand position. For installation, you will need the following metric hardware: 1. An M5x30mm bolt 2. An M5 nut with 8mm wrench flats To print this design successfully, use the specified orientation; no supports are required with a good printer, but strong bed adhesion is essential. This unusual orientation was chosen for part strength. I have made an edit to increase the build plate contact area slightly for safer printing, effective as of March 1, 2020.
