BURRIS - Signature Pos-Align Offset Insert .010

Had a Mauser side mount with misaligned holes being drilled too high (my fault). Tried 3 different scopes and none had enough elevation adjustment to compensate. After trying different combinations of these Pos-Align inserts found the right pair to give the scope a proper bore sighting. On a side note, I think these would be a great alternative to 20 degree bases on long range rifle or airguns and allow extreme fine tuning.

Don't know what the guy was talking about that couldn't make these work nor what cutting the finger out of a rubber glove has to do with using them? I have used these for a very long time. If you have a rifle that is manufactured right, barrel aligned, mount holes aligned etc., you can get 30 MOA or more in any direction without touching the windage or elevation adjustments. If you do not have such a rifle (and few do) these bushings will still enable you to align the optic with the bore even on a Remington 700. It can be time consuming but worth the effort. Once and done! It is nice to look through a scope and actually see what is intended for you to see because you do not have the lenses all cranked out of alignment with each other. If you are fooling with production rifles you need these in all three sizes. If you are not detail oriented these may not be for you. Oh, did I mention, no lapping compound all over the place!

I shoot rimfire benchrest at 100 yards outdoors during good weather. During the winter months we shoot indoors at 50 feet. Without the burris inserts my elevation would max out. I've got 1/8th inch clicks.

These Offset Inserts used in the Signature Rings allow you to correct for bases that may have been install off centered and more importantly they allow you to add from .005" to .030 incline to your scope rings. This allows you to essentialy sight your scope at 100 yrds while the internal scope adjustments are still centered, this means that how ever much internal adjustment you have it is still avalible to you for sighting in at longer ranges, if your shooting a .308 at 1000 yards a possitive .030 incline will work wonders for allowing you to sight in that far while still looking through the middle of your glass.. I have 3 sets of these mounted right now including one set I put on my 12 guage slug gun, by using these I am now able to dial my scope in out to ranges of 100 to 150 yards and the scope has remained solid with no movement in over 500 rounds of 3" slugs fired under them so far. Definetely a good product. P.S. 0 offset inserts allows you to mount your scope level and just enjoy the non marring qualities of these rings/inserts if you choose RemMax

I shoot a 30/06 Springfield M1 Garand with a scope. I tried using the system with the standard ring with no adjustment and shot about a hundred rounds. This way it did not move that I could notice in these groups. I tried both elevation adjustments and windage adjustments by doing both top, bottom, left and right individual and both together rotating font and back to get corrections I needed. I even tried the solution offered to cut a finger out of a rubber glove and they all shifted. Maybe on a less powerful or non gas operated rifle they might work fine but in my case it didn't happen.
