Burris XTR Signature Rings
The famous Signature Rings go tactical
Burris Signature Rings have been perennial best sellers for Burris, for very good reasons: the Pos-Align Inserts not only stop damage to the scope finish, they solve all sorts of alignment issues, and make it easy to get a good zero.
The XTR Signature Rings are the tactical version. They’re beefier, with six clamping screws per ring, and strong steel bases that self-center on Weaver and Picatinny rails. They feature Pos-Align Inserts – so you get easy adjustments and scope protection, like all Signature Rings.
CAN I CANT?
In order to maximize your scope's internal elevation adjustments, most long range shooters will use a tapered or canted base. Starting with a standard 20 MOA canted base means that you get an extra 20 MOA of elevation adjustment in your scope -- it's like getting a head start in your race out to 1000 yards and beyond.
You can use the XTR Signature Rings to cant your scope, but with a lot more flexibility and adjustment than you would get with a tapered base. The XTR Signature Rings come with offset inserts in 5 MOA, 10 MOA and 20 MOA. These inserts allow you to adjust your cant 5 MOA at a time, up to a whopping 40 MOA of maximum elevation gain (by combining both included sets of 20 MOA inserts).
That will save your scope's internal elevation for in-field adjusting and make dialing in those longer range shots much easier.
The XTR Signature ring inserts can be rotated to any angle, which gives you an infinite number of adjustments. Zeroing your scope is now more accurate, easier, and more precise than ever before.
You can rotate the front, rear, or both, sets of Pos-Align Inserts to get the exact point of impact you need. A small rotation can push the scope in any direction you need.
The XTR Signature Rings are sold with a booklet with detailed instructions.
