Recently purchased T6 collapsible stock for my SKS-D. Problem is that the magazine well formed steel liner can't be used with the new stock and also, fwd of clip there is a large space in the lower forestock that exposes the barrel that I think is filled if you use a specific 5 rnd detachable clip. Does anyone know of a company that makes a filler piece for this area and a liner of the correct size or do I need to consult a gunsmith?
