So, I've been thinking of checking out the new g&g GBBR. To those of you who don't know, the g&g GBB m4s are just their popular combat machine external AEG body, with the ghk gas blowback conversion kit installed. I really would like to get it, but 400 FPS is too hot for my local cqb place. I don't even know if it's possible, but can I install an NPAS valve in the gun? I don't know if if would fit, as the gas system is in the shape of a v2 gearbox.
