Knex Gun Concept (lever Semi-auto)

Hello, everybody. I know I haven't been active for a while,thats because I couldn't think of anything to make. But, then i got an idea for a new concept I don't think anybody has done it before.This is an unfinished version of the gun and its my first made prototype so I don't want to hear any bad comments so hear is how the gun works.


When you hold the gun (shown in second pic) you push the lever into the handle by closing your hand (shown in 3rd pic) that fires one shot. Then you release your grip and return to the holding point,that wil reload or pull back the pin (This has not been come-up with yet but i have an idea of how to do that) and it will be ready to fire again.
