Sorry for not posting anything lately, I have been building a long time on this gun.
This is what I like to call the MM-PASS which stands for:
Mr. Muggle's-Pump Action Single Shot.
I wanted to make a pump action single shot so that I could increase the amount of bands that I can pull back. I feel like the pump action feature also slightly increases the fire rate because you can keep your hand on the pump while you can't keep your hand on the firing pin of a regular gun. So that's why I made an ammo storage on the front, I focused on quick reload simple but sturdy design and power/range. This gun also has the chamber principle like the Untangle, which enables you to put more bands on the gun.
Credit to mepain for inspiration and a bit for the pump design, I didn't copy anything.
PS: If I'll ever post an instructable of this, I will improve the handle and the stock because as I said I wanted to keep the design simple and focus on the gun itself.
PPS: The gun looks a bit bend in the picture... I don't know why because it really isn't in real life....
Tell me what you think.
