I've got a GHK AK-47 GBB, I have a weird problem with some new ones I bought. All 5 of them are the same, it's like there is no regulation at all. The first shots are coming out at 480 fps with 0.25 BB's. This rapidly falls off to the point where the CO2 is empty before the mag is even half empty, about 20 shots. I've tried to search for this but it's very difficult to describe in a way that gives Google results! Has anyone seen this before?
