After a lot of research I just finished rebuilding my uncle's old Winchester model 1890/1906. The 1890 & 1906 parts are almost interchangeable so there lots of parts online. After re-lining the barrel, I replaced the receiver, the bolt, firing pin, main spring, hammer, trigger, inner magazine tube, the front magazine tube hanger and numerous other small parts. I also had to repair a large crack in the butt stock. Tried sighting it in but it was shooting 3"-4" to the right. I tapped the f/sight until it fell off. After more research it was determined that the barrel needed to be straightened. With my friend holding the barrel on a couple of blocks on the anvil I took an 8# sledge and hit it until it was zeroed in. It's UGLY but that's the way I got it and it is now a tack driver.
