The Knex Snapper

This small yet powerful gun for its size is small enough to fit into your pocket! It uses minimal pieces and provides a nice *snap* sound when fired. This is my first instructable ever so please try to keep the comments on the nice side. This gun shoots about 30ft. Feel free to mod it and add things but please give me credit if you make an instructable!

As I finished this design, i noticed if you point the gun down with a bullet in, the bullet will fall out. Here is my solution.

    :-( :-( ok, for starters: 1. this gun is not powerful unless you put over 15 rubberbands on the firing pin. 2. this gun is really simple 3. it is a basic block trigger 4. it stinks.

    be nice people. this is a basic gun. its well made, and its a good ible. just because it cant kill small animals or break bottles doesnt mean its a valid gun.
