Add a stop, otherwise at best that extension spring will stretch out, at worst the bolt will follow the projectile out of the barrel, I know :roll:

since a stop may get in the way of the ammo, I'm going to have a wire inside the spring that is only as long as as far as I want the spring to go. Also, I've added a push-button trigger, and cast a small piston. I need some CPVC parts that I will probably pick up this weekend to start the BFB housing/magazine/ barrel. And I'm officially out of CO2, too many crazed dry-firings :lol:

Double-post for an updated picture:

Lowes didn't have CPVC parts, so the loading mech waits...
