I pulled my 7.62c39 barrel, turned off the rear sight base in my lathe, and reinstalled it. Then I put it into an extra CZ stock I had,,,and American Sporter stock with higher comb for scope use. It also happens to be one of the highly figured stocks that came on the early batch of .221 FireBall CZ 527s. So now, I have a very nice accurate CZ 527 American Sporter in 7.62x39,,,,,MUCH BETTER for scope use!,,,,,and ACCURATE.
This picture shows a T36 Weaver mounted but it's only for load testing for my 59 year old eyes. A Leupold 2.5-8 matt or 4X wait to be mounted next!
