Semi or fully automatic knex gun.
I know you people don't believe anything without pictures, but, I DON'T CARE!!! I have a video! I promise! Ok, this is a semi-automatic. Pull trigger, boom, pull trigger, boom. That is it, no pulling back the ram or anything. I have not made the fully automatic version, but all it needs is a motor on the trigger and it will be fully automatic!!!!!!
If any one wishes to post instructions on this gun, I hereby give you permission as long as you give me credit. Watch the video here
