ok my English is not good at all but ill try to be clear guys.
ok i have a JG M4 S-System
i have the battery full charge but !!! when i put a Mid cap (130 rnd) the first 5 or 10 shoots in semi they just fall down from the barrel....
then i switch to full auto and then the distant go better and better and then the last 10 shoots in the magazine go all the way perfect. !!!
when i used a Hi-cap works fine but you can still notice some go perfect the 150ft and some drop down not even the 80ft.
so far no jams, the gearbox is working fine.
*my own guess is that maybe the Bucking is to hard bcuz is a (hard type). and need some time to do better. (i don't know)
1 more thing. i have a 2 piece hop up , and the stock hop up its shit !!! its to hard to adjust it. and the gears in the hop up don't even move together.
some help or any idea???
