AUG gearbox parts

Hi guys,

I’m quite new to gel blasters, I’m looking at upgrading my AUG but it’s hard to find separate parts for gearboxes.

I’m wondering if the vector gearboxes are the same as the AUG?
Gen 8, gen 9, jinming, FB, New well. It’s all gibberish to me at the moment. Every time I look I mostly get m4 stuff.

What can and can’t go in AUG gearboxes. I want to buy a spare set of metal gears for the kit I bought but don’t know the ratios etc.

Cheers,

Kaino
