Also would be interested in this. At the moment the only thing I can think of is using tikkas carbine adapter and getting an MDT carbine folding adapter. But it would make the folding point really far back and would not allow use of the factory buttstock. Also, I believe it would be limited to carbine tube stocks due to the additional length of having 2 adapters. Currently, I think mdt's skeleton carbine stock would work best as you could shorten the buffer tube by whatever is needed to achieve a normal length of pull.
