I actually liked the square cut sights with the click adjustment on the older barrels. The newer ones now have a screw you loosen then "slide with your finger" for both elevation and windage which is not nearly as accurate in making small adjustments to it. I was going to sight my irons before I put the scope on my new .30/30 barrel since you never know if you could bump it out of line. What do you guys think of the old versus new iron sights?
