So before you go on rants about how bad g and g is already know how bad they are,so please keep those style comments to yourself. I bought this gun for fifty dollars and right as I got it I put in an ics infinite motor. I was able to get about a hundred fifty rounds through it before it stopped shooting. When I pull the trigger it sounds like it wants to shoot. Also there's a small pin(not a body pin)missing near the trigger will this affect the gun if I take it apart without that pin?
