Saw a conversion a couple of years ago at a gun show in Medina OH. The guy had taken a Oly OA93 with the chopped BCG, put a 20 inch barrel on it,made a buttpad at the end, and put a pistol grip with a trigger on the hand guard with a linkage to go back to the rear. Was an interesting gun. He had it for sale for 1800 bucks.
