[HawaiianPenguin]

There are certain rules to make a gun a "stock gun"

1) Your ball feeding mechanism. You cannot have a hopper. Or a vertical contrapment that feeds your ball. You have to have a Horizontal tube that holds up to 20 balls as a loader

2) The gun must be a pump

3) your source of air must be 12 grams

Those are just the 3 main basics....there are many more tho

[kensei]

those are pretty much universal... but exceptions are somtimes made for small stick feeds. there are a lot of rules that vary from place to place, about maximum barrel length, the legality of barrel porting, multiple barrels, silencers, pyrotechnic devices, ball caliber, etc. usually not too strict.
