Really Short Handstop (No Hardware Needed)

thingiverse

I modified another "handstop" that was a bit too long for my purposes, so I think this one will do the trick. One side features a notch designed to provide a more secure grip, ideally placed on the front as seen in the Thingiverse image; however, feel free to experiment with different grip styles if you prefer something unconventional. This design originated due to the unique pumping mechanism of the Crosman M4-177. Traditional grips would often collide with the barrel during pumping, preventing the handguard from moving sufficiently to allow air to flow in.
