It is 350 fps max and hpa rifles have to be semi locked. The fps is tested with .20 gram bbs.
It's 350 fps. And they will check
350 fps with a .20 gram 6mm bb
350 fps nothing over, most make 5 shots consectively, for polarstars, gbb, and aegs
350 fps. They are pretty strict- have to test under 355 for five consecutive shots.
250 fps I think?
