Could be done...would require mods to the rifle tho.
Those "PDS/W"s are piston driven with a shorter BC. been looking into making one myself, but am still having trouble finding out how the recoil works, since there isnt a buffer assy.
im guessing it would have to be a shortened internal buffer? Just enough to shoot the bcg back into battery... interesting tho, either way. If someone knows exactly how this whole setup works, id love to learn.
