My inital thought on this bolt was the same as many i've read, Bolt was too short! however i get nice and close to my gun when i shoot, so the shorter bolt is nice, since it doesnt come out the back of the gun you wont crack your mask when it loads the next ball. I had one bolt actually break, called sam and explained the situation, i recieved a new bolt in a week at no cost. I've been using that bolt for the last 1.5 years without a problem.
Anything Vapor is a good idea, He doesnt charge alot and his products and back with great service, and are good quality. Always nice to see someone stand behind their work and take pride in it!!!
