Installed in a snap. It's solid and looks great. Nice low mount and scope is right in front of my eye when I shoulder the rifle. Only hang-up, which is due to my expectations that a mount with such fine machining tolerances would be "on zero," or close, when mounted. I was surprised at how much I adjusted the windage while siting in. I've got about 300 clicks of adjustment in my Bushnell Elite 4200 3-9x40. I counted clicks and adjusted it to the 150th click (average of range, or assumed approximate zero) before mounting the scope. I had to adjust 50 clicks or so to get my shots centered. I expected this adjustment would be less. No problems with scope twisting reticle out of level when tightening ring cap screws. All-in-all, best scope mount I've owned, but I've only owned the $16-20 variety. This one inspires confidence. Need to get back to the range to confirm it's holding zero. I had 1.125 - 2" groups at 100, shooting Fiocchi 165 gr. Sierra Game King HPBTs, 1" groups with hand-loads. Best yet for me and this Rem 710 30-06.
Pros: easy, light, solid, one-piece
