From the custom shop buy out by PTG. I purchased a few barreled receivers, this one had a nice PTG bolt assembly, had to put a firing pin, extractor and ejector in, all PTG items. Squared and Trued, scope/rail holes opened to 8/40, bolt stop also installed, no more crappy 700 bolt stop…nice fit no slop, nice and smooth. 850$ shipped to a FFL
