I have a set on my Sako and find they are unique on how they look without any screws on the rings. When the top cap is set in place it"™s amazing on how little you see of the seam. The machining is very precise with good workmanship. They are a little tricky to installing so I wouldn"™t suggest to mount them on a rifle if you would be planning on changing the optics to often. I would mind getting another set for maybe a new rifle...
