I think it is a different brand/make of vector to the LH. The selector is in a different location, down in the lower receiver not in the upper.
The charging handle, and a few other little different designs on it compared to the LH vector I am familiar with, they also do not look like any available aftermarket parts I have seen.
If it is a completely metal gearbox version it should be a pretty solid gearbox. There is alot of meat in them so shouldnāt be a problem there. The electronics is any ones guess as to how long that lasts, as all stock circuits we have seen are puss.
I mean, if you want a metal gearbox vector without the fuss of building an MK box with a LH vector, not terrible value, provided it has a degree of reliability, again any ones guess, time would tell, but at this price I canāt imagine seeing many around.
My LH Vector that is getting the MK box, T238, shs gears, and neo motor, would over $800 at full retail rates, excluding external parts, and not including labour to build it. It will outperform the GBU one sure, but so far it already owes me many hours, and I still have to wire it up and assemble it.
I can say, that the LH felt VERY solid once the MK box was in it, and quite hefty in weight.
I know in airsoft vectors are pretty much all Krytacs, and the GBU one doesnāt look like any Krytac I have seen, so likely a new small scale offering. Anyone buying one better hope it lasts cause there isnāt going to be spare parts if there is anything proprietary in it that breaks. Near $1000 gamble anyone?
I much sooner recommend a LH with an MK build buy a professional for not much more than it, least it will last, perform, and have spares available.
