That's a good looking conversion. I cringed at first when i saw another Mosin cut up, but I've got a safe full of them in varying condition and build years. The later years are find to convert, IMHO, due to the high number of them made and the piss poor job they did machining them. Corners were cut and they put out the best rifle they could at the lowest cost and as quickly as possible.
I bought one at Dunhams a few years ago on Black Friday...well, 7 of them actually, for $70 each. The kid behind the counter broke the stock on one as he dropped it in the box...split the stock about 4 inches long from the butt forward. I ended up selling that one for $150 and the guy threw in a Mossberg 722 that hadn't been cleaned in the two years he had it...he even lost the factory sights. They guy sporterized the Mosin, and Mossberg sent me the sights for the 722. I cleaned that rifle up and sold it for another $100. I made $180 from that Mosin. LOL
Anyway, the guy did a piss poor job on his conversion...to the point that it won't even fire now.
You, however, gave that old rifle some love and made it into something that, had this technology and money had been available at the time, Vasily Zaytsev would be proud to shoot. Bravo on your hard work.
