Tough Burris Tactical Rings with Inserts — Best Option for PRS?
For years we have touted the advantages of Burris Signature rings, with polymer Pos-Align Inserts. PRS/NRL shooters take not — this technology is available in a beefier, heavy-duty ring system for tactical rifles. The impressive 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.

What isn’t mentioned is that these rings do not return to zero. Mount a scope with them, take the scope off and put it back on and the scope points in a different direction. Burris clearly have paid no attention to user feedback on this product. I mark it as 4/10.
Editor: We disagree 100% and so do over the vast majority of the owner/reviewers. I suspect you did not have the inserts matched correctly or there was something wrong with your rail or you didn’t tension the crossbolts with the correct procedure. I have dismounted a scope held in these rings, put it back on, shot it at 600 yards and the horizontal zero was perfect and the vertical was changed one 1/4-MOA click from previous 600-yard session, and that can easily be due to temp/humidity changes.
There are 69 reviews of this product on MidwayUSA from actual buyers. Total rating 4.6 out of 5 stars, with the vast majority at 5 stars. Read the reviews — many of the 46 state how the product returns perfectly to zero. Here are just two of many hugely positive comments: “They hold zero, protect your scope from marring and allow you to center your reticle without using up your turrets adjustments. Just may be the best rings for long range target rifles that you can buy” and “Bought these rings to mount an expensive Swarovski scope on my Ruger SR 762 (AR 10). I bought the extra high rings. The polymer insets allowed me to cant and zero the scope without using hardly any internal adjustment left and right. Also I added 20 moa of up cant to leave plenty of up travel. The inserts make it so you never need to shim, and they lock the scope in tight with no scratches or scope damage. In my opinion, they are the best rings you can buy.”
On Amazon, you can read scores of buyer reviews, again over-whelmingly positive — 4.5 stars overall with 81% Five-star. Many users stating these are the best rings they’ve ever owned and the inserts allow handy long-range elevation. I suggest to readers that they read the reviews.
These rings are designed for true Picatinny rails. Some “Weaver-style” rails are not dimensionally correct. I suspect the poster’s issue was having the wrong style rail.
I have them on a F-Open rifle (7.62 x 54r) , and a F-TR gun (Kelby.308) , and have had no issues with either in over three years .Just follow the instructions and they work just fine . I give the five stars across the board .
Buy with confidence. I have been using these rings on multiple rifles for years. I have taken the rings (still holding the scope) off a rifle for transport, and put them back on again. No problem. Zero maintained. I use this XTRs or signature Zees for virtually all my rifles now. They give you extra MOA, allow you to compensate for alignment issue. I suspect the guy who complained did not torque the base clamps to procedure, or maybe he removed the scope itself from the ring set — that can jiggle the polymer inserts.
