lol I doubt theres a problem with the actual E2 unless its been capped or something, get some1 that you know has fast fingers to have a tinker and see what they can rack up. Also I think theres a limit to what E2s will dry fire with the eye off etc. I think with the eye off it will fire only 12 bps, at least thats what my mates does, but again could be to do with capping etc...
