The bolt, I'm not sure. It had very sharp edges all over. But it did 'match' the barrel, headspace wise.
The sharp edges chewed up the Colt pattern ejector, that had to be deburred once I noticed it.
Labor wise, if you paid someone to do the barrel & bolt work, it would cost about $100.
I have it running 100% with Colt mags now. Glock mag lower took less overall work & time.
The barrel looks like Kaw Valley, based on the engraving, but I'm not certain.
