My friend found the competitive grip uploaded by Ben49 on the Thingiverse. He liked the shape of the grip and hoped to use it on the "bushfowl" blaster. For his hope, I remodeled the grip. It is now available on the "bushfowl" nerf blaster. You can use the original hardware, or you can replace the pin with a 40mm length one, and the screw unchange. I am still not very skilled in engraving, and the finished surface may need to be trimmed with sandpaper and files.
