Very nice sights - Ultradyne Folding C2 Picatinny Front/Rear Sight Combo

I like these a lot. All metal, light yet solid. They snap soundly into place. Up or down. Adjusting for elevation or windage is by knobs who are unlikely to get moved by bumping them or having something snag on them. There is a nice tactile click when making changes. I got the loop front post which is unusual but nice as you can see the whole target.
