hi romacarter. I'm happy that I have someone here in steemit who shares my passion for airsoft. Here in the Philippines, the maximum regulation speed is 450 feet per second. I don't know what it is in meters per second. You can only play beyond this limit if it's milsim game. In my experience beyond 450 you will experience issues with your gun like hairline fractures of your gearbox, broken piston body and gears. So I try to limit my power between 380 and 420 to avoid constant breakdown.
