I was cleaning my SU-16 and I got to thinking about the possibilities of this rifle. I was wondering for those of you that are much more knowledgeable about firearms than I am, if it is possible for someone to create a pistol grip stock for this gun? It does not seem like it would be that difficult from what I could see, if someone just replaced the part of the stock that folds under the receiver. I was just curious of what you all think.
