Nerf Picatinny Angled Foregrip by Captainslug
This model is imported from Thingiverse, see the original here: Nerf Caliburn - Picatinny Angled Foregrip by captainslug - Thingiverse
Angled foregrip by Captainslug styled and designed to match the Nerf Caliburn Homemade. The "Core" part can either be tapped for UNF 10-32, or you drill the hole out to .205".
Slide the foregrip over the rail segment, then slide the "Core" part in through the opening in the side to lock it into the rails. Secure the "Core" to the foregrip using a screw and optionally a locking hex nut.
The foregrip also alternatively includes a through hole at the rear if you just want to use the typical through-bolt mounting method.
Post-Printing
Inside of the foregrip will usually require filing or touch up with a rasp.
