Nice ring all around. It is a super low profile ring, probably not the best one around if you want to cowitness with a back up sight on an AR-15, but as a stand alone, the use of this ring will get your sight picture / cheek weld down as low as you possibly can. I used mine with an Aimpoint M2. My only gripe is the overall price - pretty high, but, I did specifically want Aimpoint rings - gotta' pay to play I guess,
Pros: Very, very low mount, very well made
Cons: Cost
