GHK Ak74u upgrade/part options?

[tdotsofter]

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!

First thing you'll want is a steel sear and firing pin. I'm running the GBL unit with barrel in my AKM and I've been very happy with the performance. for O-rings I've had good luck with http://www.oringsandmore.com/ fairly quick delivery, and the price is right.

have you figured out the orings for the co2 valves?

besides the two they have on the samoon site no. The main opening of the vale has a piece of nylon, and I'm not sure what they're using for the seal inside. I'm trying to sell the CO2 mags I have and they work so I don't wanna fuck around with them.
