I decided to make a fully automatic gun (but again, sadly i dont even have half the pieces to do this outside the ldd) after i watched a lego uzi on youtube or somewhere. so i was starting to think of what the mech would be, and i remembered i've seen a good internal mech by Chas Iris. so i used that, but with a little edit: full-auto, not semi-auto
check it out and say what you think in the comment section. and rate too would be nice.
