Today was a long time coming — much longer than I anticipated. But I learned a lot about problems with the Diana 27 that I have never encountered before, and I now believe I can tune one with ease.
Recap
Just so you remember, I am tuning reader Michael’s Winchester 427 that is a Diana 27 by another name. It looked good on the outside, apart from missing things like the rubber button on the butt and a locking screw for the pivot bolt. The rear sight was a kluge of backwoods “repairs”, but that didn’t impress me until the very end of the job. In fact, I will tell you now that I should have started there first. It was the main source of the rifle’s issues.
