Signature Rings also accept Pos-Align Offset Inserts so you can virtually sight-in your gun without moving the scope adjustments. Lens systems perform at their optimum when all lenses are optically centered. By keeping the internal optics centered, you'll see through the scope all of the clarity, sharpness, and brightness that the optics designers intended for you to see. The offset inserts also correct for any mis-alignment caused by receiver holes drilled off center, or the bases or rings being slightly off perfect center. And for you 1000 yard and other long range shooters, the need for expensive tapered bases or shimming becomes a hassle and expense of the past.
Burris rings and bases have long been favorites of custom gunmakers because of their strength, beauty, and fit. It's easy to recognize Burris' leadership role in scope mounting systems when you consider the myriad of innovative designs and manufacturing processes that result in rock-solid performance. Each ring is made from a solid piece of steel with the top and bottom half perfectly mated. Zee rings with no moving parts are the best fitting and most positive gripping Weaver-style ring made.
