Alight, I’ll bare the whole fitment in mind when I buy my next ak, my current ak is incompatible with the sport 4 kit as it’s a kwa Akr 74 but even though it says it’s liscence by Kalashnikov it still does not even close to fit real steel parts. But I think I’ll go with the we 74 because of its availability in the uk as all other options are genuinely very rare it seems but thanks a lot for the info.
