I might be interested. At one time I was looking at trying to find s shorter vernier sight but never could find one. I did install a Lyman peep. I like it but it's kind if bulky. If this type works as far as elevation adjustment with the original front sight to be able to get out to 125 yds would be good. I'm shooting 440 gr lead conicals. Price??? Seen one on Ebay, bud was at 96. Lyman was 100 or 125.
