semi-auto gun system
I found this system for a semi auto gun. I used to built lego guns with this system (I also built a full-auto with that) and I've been trying to use it in a knex gun, but I cannot work it out really good. So does anyone how to use this kind of system on a knex gun.
It works like this: You pull the trigger, the spring gets pushed forwards, the spring is compressed against the ammo, but the ammo is clicked(I dont know how to call it maby stucked). When there's enough pressure the ammo will break loose and fly away because of the power of the spring.
