Iron sights, Williams peep, red dot no magnification or the new gun works sights. And I just literally switched and put a 5x25x56 nightforce on top of my cva paramount pro for a utah muley hunt I won a few years back . I'd been building points and slowly getting to the rifle while still working on other stuff . Missed it by a year it seams . It did give me a reason to get another tc encore setup so that I don't have to remove any scopes on my muzzleloaders for this hunt .
