Just saw these sights while looking for something to use on one of my guns. Looks like it would be easier to use with eyesight that isn't as conductive as it once was with iron sighting systems. Anyone have these, and if so, how do you like/dislike them? The websight says they are adjustable for windage and elevation, but i don't see how they are doing that, unless it's by adjusting front bead, and that would be a no-go for me, if that is the case. Don't know how to post a link, but they are on truglo's web page under shotgun sights, also on amazon and i few others. Thanks for any info!
