komrads, my question is what reasonable gearbox choices to buy for replacement of broken cm35 gearbox with least hastle of installation. can i use kalash gearbox, jg or deepfire v3 gearbox?tnx in advance

I have 2 new KALASH /BOYI in reserve in case i have to change AK GB , and they are not strong :320 FPS , good for AKSU and have nice sound
I have replace theem also on my AIMS ...even plastic bushing

for cm35, choice a near or exact tm version 3 gb, like jg or tm or df gb, not the vfc or kalash.

I have replace the UNICORN GB AKSU by the KALASH , still GB v 3 it fits very well
You can replace your GB by any GB V 3 made to fit an AK but the JG or the CYMA a little bit strong for a short barrel AEG

tnx komrads, more inputs would help.ive read somewhere tat jg v3 gearbox has problems with selector lever when installing on cyma receiver cm35.

No use to take an GB with a strong spring all the more since your inner barrel is short
My BOYI GB works very well , i have 4 AK with that GB ( for some of them i have prefered to pull out the 380-400 FPS CYMA s GB ) so that it is not going to hurt players

what about the kalash/dboys AK?
what brand of gearbox would be compatible?
i plan to replace it with ENERGY or CA brand of gearbox.

I do not now much about CA or energy , but it "should " work if it is named GBv3
