Tactical Tech: New XTR Signature Rings from Burris
For years we have touted the advantages of Burris Signature rings, with polymer Pos-Align Inserts. Now this system is available in a beefier, heavy-duty ring system for tactical rifles. The new Burris XTR Signature Rings offer six (6) clamping bolts per ring plus strong, dual steel base-clamps that self-center on Weaver or Picatinny rails. These aluminum XTR Signature Rings provide strength and holding power, plus the key benefits of Pos-Align inserts. As impressive as XTR rings are — they aren’t that expensive, with 1″-diameter XTRs starting at about $90.00 per pair (30mm and 34mm XTRs cost a bit more).
The polymer inserts in Signature rings perform three key functions. First, the inserts provide full, uniform scope-to-ring contact, with no need for lapping. You get a very secure “grip” on your scope without ring marks. Second, the Pos-Align inserts can provide elevation “pre-load”. With eccentric (offset) inserts, you can raise the back of the scope relative to the front, gaining up to 54 MOA of built-in elevation, without the need for expensive tapered bases. Third, the offset inserts can be rotated clockwise or counter-clockwise to shift point of impact. This lets you zero your rifle easily while keeping the turrets in the center of their travel.
Burris XTR Signature Rings are offered in 1″, 30mm, and 34mm diameters, and three (3) different heights: 1″, 1.25″, and 1.5″. Each ring set includes two sets of concentric inserts and one set each of the following offset inserts: +/-5 MOA, +/-10 MOA, +/-20 MOA. These allow you to “pre-load” elevation and/or center up your cross-hairs.
– Pre-load Elevation. No need for expensive tapered bases for long-range shooting.
– Correct misalignment caused by off-center receiver holes.
– Correct for bases or rings being slightly off-center.
How to Pre-load Elevation
To add elevation, set the Pos-Align Offset Inserts to raise the rear of the scope and lower the front. As long as there remains sufficient clearance between the front objective bell and the barrel, Burris recommends lowering the front of the scope the most and raising the rear of the scope the least. The amount of actual elevation “pre-load” will depend on the ring spacing (see chart). In the illustration, with 4.75 inches between ring centers, a +/- 20 MOA pair in the front combined with a -/+ 5 MOA pair in the rear will yield +25 MOA of total elevation. (If the rings are positioned further apart, you’ll get less elevation pre-load.)
Using Inserts to Adjust Point of Impact in Any Direction
Although it is convenient and most understandable to refer to the ring inserts as a “bottom” or “top” insert, the inserts may be rotated to any angle within the scope rings. This allows the shooter to correct the point-of-impact in any direction. The drawings below show how the inserts can be rotated to induce both elevation and windage changes at the same time.

Wouldn’t this system of offset inserts put undue stress on the scope tube?
I had the same question as Aziz, but looking at the diagrams of the rings/inserts, I believe that the inserts can be oriented within the rings such that their front/back edges are not parallel with the front/back edges of the rings. The result would be similar to a heim joint, whereupon there is a semi-spherical insert in an internally grooved (to match the contour of the spherical portion of the insert) eye, and the insert can be oriented such that its parallel surfaces are NOT parallel with the flat sides of the eye. I know that the text description doesn’t make much sense, but if you look up images of heim joints, you’ll be able to picture what I am saying.
I have these rings on both a “F”-Open rifle ,and a L/R Tactical rifle . Both are .308’s and I haven’t seen any scope tube degradation on either scope . Not even any ring marks . The inserts haven’t slipped any , nor has either scope moved , or rotated . Just exercise care , and follow the instructions during the installation . Take your time and torque correctly . No heavy-handed Gorillas need apply .
Where are they made?
Owning three sets of the XTR’s I never considered where they were made , but your question made me go look for that info . They are made in china , sadly to say . But I honestly wouldn’t care if they were made on the dark side of the Moon . THEY WORK , as advertised , and better . I’ve shot over twenty thousand rounds under these rings , and none of my scopes have moved , or had to be adjusted .
