So...just picked up an older (2001) Lwt SA Champion. This one has the GI guide rod with the reverse plug. The plug is also used with the regular guide rod and has the hole in the end. Is there somewhere I can buy a reverse plug without the hole? Also, does anyone know what rear sight cuts these have? The first pic is of the plug I have now. I would really like to find the one pictured in the second pic which covers the gap under the barrel.
