King arms SIG 556 electric blow back

[Rifleman7]

Hi all! Picked up a SIG 556 very cheap, but doesn’t work stripped it down gearbox is nuked. Obviously requires a replacement but not sure what type of gearbox it takes. Some things I’ve found say V2 some say V3.
Also noticed has an extremely long nozzle.
Is there anything to replace it with or is it bricked ?
Thanks in Advance

Click to shrink...

It's a customised proprietary derivative of V3 - so you would need an identical OEM shell.

If you have Negative Airsoft on patreon - brand enforcer 124 and 125 detail one of these and from the looks of it - he managed to get a standard V3 to fit. There's probably a lot of bullshittery involved [not including the fact he rips off his fingernail with the electric blowback not realising it has it lol]
