Another new k'nex machine gun
Right here goes,
You have arms 'thing that holds string' attached to the barrel by a hinge, there is a spring or rubber band underneath, when you pull the trigger the arms let go of something that keeps them back, the spring (or rubber band) will fling up making the string taught, which pushes the firing pin. The arms also push forward the slides on rails, they hit the springs at the left side and rebound with enough force to push the arms back down, then repeat.
-It's quite compact
-I'm thinking it might be powerful
-and if someone makes the mech IÃÂ¢Ã¢ï¿½Â¬Ã¢ï¿½Â¢ll put it in an L85A2.
-Hard to make
-Brain-bogglingly difficult to understand (just think about it a few hundred times and that's me!)
I hope the drawing's detailed enough, sorry bout no pics of the real thing (I'm not very good at fixing things together).
Hope someone makes this.
If you don't understand or are just wondering bout something just post a comment.
