Thanks for the compliments. The gun shot okay at the match; it seems I need to file the front post more to get elevation set. The kits were for sale by a local shop; they had been sitting on them for awhile at around $450 but blew them out for about $250 and I couldn't get the CC out fast enough, they only lasted about two hours. I know of some other vendors who had them when I was price shopping but they are either now sold out or far more expensive ($600-800).
