Airsoft Canada - View Single Post - CYMA CM046 Ak47 - How do I Downgrade the Spring with Electric Blowback Gearbox

Bar1975 · December 3rd, 2012, 09:51

Hey guys.. i just purchased this AEG and absolutely love it so far. I didn't realize how powerful it was and as a result will need to downgrade the spring so that i can use it on the field i play at. (<400FPS with .2g)

Anyways.. I've got lots of experience working on Version 2 and 3 gearboxes but i have zero experience with this electric blowback mechanism. I started to tear down the gun last night and just had to stop. I have no idea what I'm at right now. I can't find ANYTHING online in regards to changing out a spring in a gear box that also has this EBB feature. I believe it's a pneumatic blowback so it's all built into the gearbox itself. I don't believe i can simply crack open the gearbox without first taking apart this EBB.

Does anybody have any references or advise on this?
