GHK Ak74u upgrade/part options?
GHK users, I just recently picked up a 74u but would like to now get into the upgrading stage. Hopup/ barrel combo.. which is the best route? GBL iron man unit? TNT hopup/barrel combo? or rhop? or could the Rhop be included in the other 2 aswell? Now Orings/parts Looking into getting a cqb nozzle and a field nozzle which should I grab? lastly Orings, 2 of my mags are leaking from the valve..where should I grab all of those rings!
