Knex hammer action pistol
Here is my knex H.A.S.A, that stands for hammer action side arm. It can shoot 15-20ft with one rubberband. It just a single shot hammer action pistol. I do have a reason why I post this one. The mechanism can be made much smaller and more compact, being able to fit in a Colt realistic revolver shell. All you'd need to build is the revolver out of grey spacers and scotch tape. It could be done, I may or may not try and build one. Whatcha guys think?
