I believe the gearbox from this boyi will last long even with a spring upgrade (except for sp140/150 and up of course). Alot of ppl in my country and I, use china V3 mechboxes (cyma,jg). And these chinese made V3 mekboxs can handle upgrade springs well (up to 500++fps). I think 400fps won't be a problem for this gearbox, also considering that spring alone is not the only factor that affects muzzle velocity.

V3 GBs are easier to deal with compared to the V2 ones imo. AK, G36, and AUG gearboxes are also easier to access compared to M4 variants. You won't have a problem with V3s if you can deal with V2s.

ic, any info about the performance of the gun? (feeding,rof,accuracy,hop,etc) tnx

I'm planning to buy a Cyma AKS-74u, I think it's available in our country. The BOYI version is not out in my country yet, and I would love to hear about your opinion; should I get the CYMA AKS-74u, or should I wait for the BOYI version? Which gun would be better in a real game? Thank you!
