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...
