I needed to sand the concave indentations on the base of both front and back sights....i used a dowel with tape wrapped around it to get to almost the same diameter as the rifle barrel, wrapped a piece of sand paper around it, then worked them into shape. A good cleaning of the parts with alcohol swabs, then a coating with 30 minute epoxy, and the sights were attached to the rifle. I gave this a couple days to set up good, and went out to the range today.
While at the range zeroing in the sights, I learned a couple things. 1st, my eyesight at 35 isn't what it used to be...I can't believe I'm saying that already. 2nd, as with all aspects of shooting, I've found, shooting with irons isn't as easy as it is 'in theory'. It was good fun however, and while my results don't compare with my groups while 'scoped', I'm still happy. More practice, and i'm sure these will tighten up.
50 yards, 22lr, iron sights...not too bad, could take home dinner with this if I needed to. This sure is a fun hobby!
