Hey guys I'm new to the forum been playing for a bit and decided to give the forum a try. Anyways I bought a brand new Echo 1 CPW AK 47, the promble I'm having is it shoots 2+ bbs at a time on semi-auto. Now I know what your next question is that is 2+ bbs per 1 cycle (not motor or gearbox but a feeding issue). Sometimes its fine and feeds 1 per cycle other times it shoots out 5 per cycle. Now when I put it on full auto it seems to shoot fine, but does randonomly spits out 2+ bbs for 1 cycle if that makes sense. I've notice that certain bbs will do it worst then others and some rarely do it( all are .20g) and my mid caps effect it more that my hi caps. I've had the gun not that long maybe put aprox. 5,000rds in it. look at the internals and can't see any noticeable damaged parts. I'm think it might be the hop up but not 100% on it. just wondering what you guys think. And maybe advice on whatever to replace/ upgrade. Thanks
