As long as it chronos at 400 with .20 youre fine, any higher and youll to be semi only and fire from 100 ft
NO, because of joule creep when firing hevier bbs. Also even without worrying about joule creep it would have to be semi and 450 or under for dmr. The 500 fps limit is only for bolt action snipers
If it chronos with a .20 gram at 390, I believe so.
