I recently purchased a Rock River lower half and removed stock, buffer exension tube, buffer and spring. And end plate. Had loctite on threads! Tube has a few scratches on threads, was very difficult to remove with new wrench. Will sell complete for $65.00 shipped. (SPF) Thank-You.
P.S. money back guarantee, if not satisfied with stock assy.
edited to add, this is a 6 psition colaspable stock.
