Nope, the K is different from full size MP5s, in that it uses a V3 gearbox, but with a long type motor. For a disassembly and detailed view inside you can check it out here: https://rockoairsoft.blog.hu/2017/03/06/jg_mp5k (Just bear in mind you'll need to translate from Hungarian).

Doesn't the MP5K use a V3 gearbox, though?

I think someone must have had a word with him, or his drugs have worn off, as it's no longer on the discord. 😂

Oh wait, it comes with a spare ambidextrous mag release. That explains the price!

It is indeed. I don't know if he's a chancer or just deluded!

£300 for a "SCAR-H / UMP hybrid" (aka a double eagle UTR.45). 🤡

Are they actual lenses made to a prescription, or an insert?

Any chance of some pictures from the inside, please? Do you think there's any scope for prescription inserts in these?

Picked up a Steyr scout second-hand yesterday. Used to have one, sold it as I had too many bolt actions. Sold most of those, missed the scout and saw this at a good price. Was very dirty inside, missing a screw on the trigger unit, but after a disassemble and cleaning is now running smoothly and putting out 2.2J on a 0.45. Just need to test it out now!

I'm going to take a guess and say that you might have got an adapter wired up for RC cars, which will be reversed. I've had them myself, but caught it beforehand luckily, and seen plenty of people caught out by this. IIRC, the larger sized contact on the deans should go to the round contact on the mini Tamiya. Can you post a photo to confirm? Also, put the affected batteries outside somewhere safe! I believe the correct protocol is to cut off the contacts (one wire at a time) and then put it in a bucket of saltwater, but others can confirm.

Message me tomorrow with what you need and I'll see what I have.

Not wanting to jinx myself, I've been lucky enough with my VZ58s to get away with just a bucking and barrel change for most of the 7+ years I've had them. The ETU is where I've had issues unfortunately! I think it would be beyond that unfortunately. IIRC, the cylinder head and nozzle sit much lower than they do on normal gearboxes, and the motor attachment is more akin to a V2, where you screw the grip directly into the gearbox shell, rather than having a motor cage. I'll try to dig out one of my spare gearboxes and get some photos. Photos of a V3 and two VZ58 boxes, with and without the trigger board & motor guide.

Unfortunately it's its own style of gearbox, so a V3 wouldn't fit. I've had the same issue in the past myself tbh and I had to message Ares directly, so that's probably your best bet; they were fairly prompt with sending out a replacement, but that was a few years ago now. I could use a couple of the mosfets myself really, so let me know how you get on if you do!
