You do realize that this has been done before, this is not an original idea. Tapco had a "drop on" pistol grip for the SKS but stopped making it. With the aftermarket stocks now available, there is not a real big market for a drop on pistol grip IMO. Also, once you add the pistol grip you are forced into the 922r game so there is no benfit for someone to buy just a pistol grip unless they wanted to keep the wood stock and replace some more expensive parts. By far, if someone wanted a pistol grip the cheapest option is to buy an aftermarket stock.
