Remember guys, when you start talking about "ring strength" it's all a lot to do about nothing. The weak link in ANY scope mount system is the 4 tiny 6-48 screws that holds the whole ball of wax to the rifle. I hear guys talk about "solid steel" this and that, "heavy cross bolt screws", etc. All of it is totally meaningless because the whole system is only as strong as it's weakest link. In actuality, having all of that heavy mass sitting on top of the rifle is going to make the whole system WEAKER not stronger, simply because you have so much more weight trying to be put into motion by recoil forces each and every time the gun fires. Those 4 tiny UNF threaded screws are going to shear long before anything else in the system fails. It's best to keep everything as light as possible. Especially with heavy tactical scopes, and heavy recoiling Magnum caliber rifles. I have never had a failure of a Burris Signature Ring in thousands of rounds. If there is any disadvantage to them it is the fact they don't look "tacticool". Considering the way they perform, I can easily live with that. Bill T.
