The stock was exactly what I was after struggling to find anything reasonably priced in the UK. I used it on my Tokyo Marui MP5K and it fits almost perfectly. The bottom bolt goes through the base of the stock adapter while the upper bolt goes more than 80% of the way through. It's secure and gives me no anxieties it will come loose, which was the case when I fielded it.
SIXmm's delivery was even faster than I had anticipated and I didn't use the premium service.
Do I recommend this stock for MP5K? For the CYMA and Tokyo Marui versions, I would say yes unreservedly though I'm very confident it would be fine with JG's version too.
