I'm going to be really pissed off if my gun doesnt fire at all the first time out. I will be going out with my Dad who was trying to get me to buy a SBE and he'll never quit giving me **** if it doesnt operate. I will, of course, be cleaning the **** out of my gun before it's ever fired. I have seen other guns that if fired as they were put together at the factory would have broken or destroyed parts. Always check your stuff out yourself or let someone who knows better than you check it out to make sure thats its safe if nothing else.
