Nice group. At 50 my eyes sure aren't what they used to be and shooting open sights is getting more difficult by the minute. Aperture sights have really helped me and that is one dandy looking setup you have there sir. Dad had to completely stop even trying open sights around my age and went to aperture for a few years then to completely relying on scopes. Looks like my vision is traveling the same path. Can't read without 1.5x reading glasses and buckhorns look like a fuzzy ball.
