yeah GBB is gonna chew on your wallet for mags..you only get like 30 per a mag so you need yeah 6 mags probably. Cause if you are playing outdoors, a lot of the shots gets blown away by wind and also if you are in cold parts of Canada..GBB is not that great...indoors i love GBBs.(RIP we don't have a indoor place no more
)
of course you need:
good eye pro - rated
good shoes - ankle protection
good clothing..just comfortable

Plate Carrier - Molle
Mag Pouch
Muzzle sock for safe zone
not TOOOOOooooo improtant, but more of milsim stuff
Camo if you are going to milsim
