I could not agree with SpeedZZ more. I spent many years studying all of the ballistics (primarily terminal), wildcatting design and scope design information I could find for many years in all my spare time and every scope expert will tell you that optimum light, contrast, etc. is achieved when the scope is at the the closest it can be to "true center" of it's adjustment. I shudder to think how many people spend hundreds or thousands of dollars per scope, only to then put them on standard mounts and adjust them 15, 20 or even 25 MOA out of the center of their adjustment to get their firearm zero'd. You might as well buy a hundred dollar scope at that point almost. Not only do these scopes allow you up to 40 MOA of adjustment (up to 20 in the front mount and up to 20 in the rear), they also provide a VERY firm grip on the scope. In fact I've never had one shift due to the polycarbonate inserts. I used to lap all my scope rings by hand to also prevent scope tube stress/slight bending. These eliminate that as well as the inserts are self aligning! Further, they 100% eliminate any scope ring marks in case you want to sell the scope later. Lastly their ability to get up to 40 minutes of angle vertical offset allow you to avoid having to buy vertical offset bases for long-distant rights. Other than my picatinny-railed Accuracy International-stocked rifle I use these in all my big-game caliber rigs and religiously encourage all my friends to try them as well. I could not endorse this product more. I am thrilled I bumped into them years ago and plan on using them as long as Burris keeps producing them!
I've been using Burris Signature rings for many years and they are by far the best rings made today. The other reviewers pointed out the sight in advantage which is very real and handy. However in addition when trying to set up the scope and turning it or pushing it forward, pulling it backward, etc., there are no nasty scratches on the scope finish. I use primarily Swarovski optics and there is nothing like tearing up the finish on one of these scopes. Swarovski quoted me $400 recently to change the external tube on a scope that had been damaged by regular steel rings.
The Signature rings are not only the best made but they are very reasonably priced. Most of the benchrest competition shooters use them and swear by them. These guys shoot tiny holes at 200 yards consistently! They swap scopes from rifle to rifle without having 'marked' the scope up in the first rifle.
I can't recommend these rings strong enough. They are great!
A little info. When you sight in a rifle scope in, you have to adjust the windage and elevation knobs. The more you "turn and click" the scopes reticle from its factory set "centered" setting with these knobs, you less clear and accurate the scope becomes. Picture a cross hair reticle in your scope. And imagine at its factory original setting you can "turn and click" the elevation and/or windage knobs 100 clicks each direction. You do this to line up and sight in the cross hair with you bullseye target. But, each time you move your reticle cross hair up/down/left/right from its original factory setting, your are moving the reticle toward the "sides" of the scope, when its better and more clear to have the reticle in the center of the scope. Now, what these burris rings allow you to do is instead of "click and turning" your elevation and windage knobs to the extremes where they are near the "sides" of the scope walls, you can FIRST adjust the scope using these plastic inserts that go between the metal rings and the scope. So lets say you shoot your rifle at the target, and your a foot high and a foot to the left. Instead of turning your windage/elevation knobs a foot each way, you put the corresponding plastic inserts in the rings to adjust the scope from the OUTSIDE of the scope, rather than internally. After you do this a few times you will be within say 4 inches of the bullseye, and NOW you adjust the final few inches using your elevation/windage knobs. And because you did very little "turn and clicking" of your knobs, your internal reticle is near the center of the scope (rather than the outside edges), and because of this it is more clear and accurate. Ask any scope expert, they will tell you in perfect world the reticle is near the center like it is when it comes from the factory. This Burris rings and inserts allow you to do this. I also recommend using a one piece base, preferably all steel (could run you 100 bucks for the steel one piece base, but its more accurate and strong). I use these rings on my Winchester 70 .270 and Rem. 700 30.06
