Thanks for the comment. I don't have any pictures of the whole gun but you can see it in full in the video. Made a stock for it but it broke :c. I tried to take as many damage pictures as possible though. Here's some more, taken from my phone.

Coffee can full of water after being shot. Marble was stopped at other end, leaving a dent. Found powdered marble in the bottom.
