Burris XTR Signature Rings 30mm
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.
INTRODUCTION TO POS-ALIGN OFFSET INSERTS TECHNOLOGY
• Provide precision customization of cant to maximize usable elevation adjustment of the scope. Included inserts allow for 5, 10, 15, 20, 25, 30, and 40 MOA of cant. The following inserts are provided: +/- 20 MOA (2 sets) +/- 5 MOA +/- 10 MOA Concentric (Zero MOA)
• When conventional rings lack proper lapping, stress can be induced in the scope tube. These stresses can cause small point-of-impact changes when subjected to extreme temperature changes. The Inserts stress-free clamping of the scope tube prevents any point-of-impact shift.
• Provide 100% scope-to-ring contact eliminating the need to lap rings.
The Pos-Align Inserts pivot within the ring while maintaining direct contact with the scope, creating more gripping power while leaving the scope unmarked.
• Lightweight aluminum ring body with solid steel dual screw clamps provides strength and reliability.
• Self-centering dual steel clamps assure proper centering of the ring and flat mounting on any Picatinny base. The clamps allow the rings to “float” to the center of the base while being tightened.
The amount of cant provided by the Offset Inserts is dependent upon the distance between the centers of the two rings. This chart provides details on how much cant each insert provides for various ring spacing
XTR SIGNATURE RINGS INSTALLATION INSTRUCTIONS
Make sure the fi rearm is unloaded. Clamp the fi rearm in a secure position. Loosely fasten the ring bases to the receiver approximately 4 inches apart. Deciding which inserts to use.
• Determine how much cant you want. Canting a scope such that the objective is lower than the eyepiece allows the shooter to use more elevation adjustment when shooting at long ranges. 1 MOA of scope adjustment equals approximately 1 inch of point-of-aim adjustment at 100 yards. Use table below to determine cant.
• You will note that each Pos-Align Offset Insert is marked with a “+” and a 5, 10 or 20, or a “–” and a 5, 10 or 20. These are made to be used as matching pairs: +5 with -5; +10 with -10; +20 with -20 in the same ring. The “+” inserts in the bottom of a ring will raise the scope and a “–” insert in the bottom of a ring will lower the scope.
• You may set the Pos-Align Offset Inserts to either raise the back of the scope and lower the front, or conversely, lower the front of the scope and raise the back of the scope. As long as there remains ample objective bell clearance to the barrel, we suggest lowering the front of the scope the most and raising the rear of the scope the least.
For example: A front ring with a –20 insert in the bottom and +20 insert on top PLUS a rear ring with a +5 insert in the bottom and -5 insert in the top will EQUAL 25 MOA of downward scope cant.
Initial Scope Placement
Turn the scope to its highest magnifi cation. Place the scope into the bottom ring inserts. Carefully shoulder the rifl e and move the scope forward or backward, positioning the scope to the maximum eye relief for comfortable viewing.
Final Scope Securing
Once the rings have been positioned as far apart as possible, tighten the bottom ring clamp screws to 40-70 inch pounds. Install the lower inserts and place the scope back in the rings. Install the upper inserts and loosely tighten the ring tops. Level the reticle and tighten the ring top screws equally so the gap between the top and bottom halves is uniform.
