Too bad they don't make an M130 kit for a GBB!!

A fellow I play with did a very similar upgrade to yours, but without the hammer spring and high flow valves. He still can't get through an entire mag either. I chalked it up to being the increased mass of the slide, as well as the slower movement of the slide. This would time the valve to be open longer, but I think the extra gas released gets used to cycle the slide and doesn't translate to extra velocity for the BB.

I hate working on gas guns, and I don't spend alot of time with them at all. So I'm only speculating here.

I'd much rather work on my PTWs, but they don't really need any. So I watch the Military Channel instead.
