Thanks. I'm 68 and wear progressive lens glasses. I've been struggling to figure out how I can have the same comb height for an XS peep sight and low-mounted scope and have concluded that it just isn't possible. Wouldn't be a big issue except that I want to thin out the gun safe and can do most all of my deer hunting with my Ruger 77/357 (because I'm in Ohio). I've always preferred to still/slip hunt with a light rifle with a receiver sight, but with the changes in deer patterns (and my knees) it's starting to look like it makes more sense to sit in blinds, at least where I am. Which seems to mean maybe it's time to give up on peeps and stick with a scope, at least for the primary deer rifle. I suppose I could always buy a second one and keep it dedicated to a peep sight. Decisions, decisions.
