K'nex Shotgun

This a K'nex shotgun that I made. To load it, you pull back the bolt on the top, then you put the shell into the chamber, and
then you close the bolt. It uses a sear trigger, because that is the only type of trigger that would work. The sear is at such
a high angle, that the pin wants to push upward. The trigger can't hold too many bands, because the pin will push up and
fire prematurely. If someone could figure out how to make the sear better, than it could hold more bands.
