good to have m120 in stock v3?

[BORDENSNIPER]

Ok so..Ive been getting tons of compliments on the AK in the field and my dad who is th main user of the gun just rapes ppl with it....so I thought....il put an m120 into it.

it is a stock ver3 cm02 kraken gearbox, with stock gears.

modiefied parts:
- nozzle
- polycarb piston
-sorbo pad
-ball bearing iston head
-ball bearing spring guide

I put an M120 into, will it be fine? (it sounds like it is shooting at same rof as before.

no problem, but honestly with a bearing piston head and bearing spring guide, it probably would go over 400fps easily

[BORDENSNIPER]

with the stock spring?

[Skladfin]

ya you can just use the stock spring(provided that it's firing at 370 right now) and add bearing piston head + spring guide + airseal nozzle

my kwa is shooting about 400-410 and compared to the ak with stok spring it outshoots it distance wise, thats why i put an m120 now its about the same...although the kwa is still straighter.

thanks for advice cheers.

stock cyma gears will probably strip with 120 spring. I had a stock JG spring in my cyma mp5 and a couple teeth on one of the gears broke off.
