WHAT?
I have no idea! LOL ill try again
If you have a tech that knows what hes doing look at a kwa, he should be able to get 490 fps out of a 120 spring in a kwa.
Iv never had a single complaint with kwa. tell me one thing in a kwa that you dont see as an upgrade part for a china gun.
ball bearing bushings, ball bearing spring guide/piston head, and piston. Low resistance wiring harness. H Type hop nub, 6.04 barrel.
all of tho's installed in a china m4, would make it "custom" yes? im not even going to start on the friggen externals. lol
thats a pretty solid build in my eyes. Yes it does need some attention to detail to perform like it should. after all it did come out of a factory slamming a shit ton out a day.
the only reason why i donnot own a KWA is because there too friggen easy and that's Dead Honest i hate KWA for that fact.
there the UTG L96 of AEG's when it comes to a easily upgradeable gun that can shoot so hot it will bury a bb in someones skin from 100 feet.
and to a responce to the thread. try checking your hop spacer (the small tubular peice), it could have shifted out of place on the hopup arm, Or it could even be too small. You can take a larger diameter piece of wire isolation cut to the right size and use that, Or try and get an actual nub.. they'll work pretty much the same
and whats your fps, the kwa 2gx seems to fail severely at around 300 fps, its a trick to get them to work at that low of fps
or try cleaning your barrel with a dry swab, you could have a bunch of excess grease or lube on the bucking
