    Has anyone used these? I like the PosAlign set-up but thought I'd try the offset inserts to pick up a little more elevation without using a 1 piece canted base.

    I use the Burris rings and inserts on most of my rifles. You can can get quite a bit of elevation by using a set of the off-set insert in the front, rear or both. Just remember that they should be installed in sets. A +10 should be mated with a -10 in the same ring; +5 with -5 and so on.

    So if I use a -10 on the bottom front and a +10 on bottom rear, that should give me about 20 MOA. Is that correct?

    More like 15 MOA, plus or minus. It depends on the distance between the rings.

    I use them in several rifles from 223 to 340 Weatherby. Burris Signature rings are very, very good and the inserts can be a huge help.

    I wish that someone made good double dovetail bases for the Weatherby Mark V, and then I'd use them even more.

    YES!!! I had problems with my Savage. Have a Vortex Viper on it and when I zeroed it at 200 yard I was left with less than 4 minutes of elevation left. Put in one of the offset inserts and now with a 200 yard zero my scope is 4 moa below its center. They definatly worked for me.

    I uused these on my 6.5-06ai first I put the 20 moa base on . I still had 47 clicks to bottom out so I put a 20 & the 10 on to raise it another 10 moa
    had to use both to raise scope up off of base

    Hey Krumfola,

    Your're very welcome. I hope you find it to be useful.

    I use 30mm Burris Signature Zee rings with my 300WM and mount a Horus Falcon with the H37 reticle on an EGW picatinny flat rail. The 30mm signature rings are a lot stouter than the 1 inch rings. This enables me to place them closer together than I would with regular rings. The H37 reticle inside the rigid steel body of my Horus Falcon gives me 4mils to begin with (17.4moa). Add to that the 19.3 moa with a 3.55 inch spacing (9 picatinny slots)and I get 36.7moa without having to touch my elevation adjustment.

    Pretty kewl ,I'm happy with that!:D

    When I get 'serious' I'll probably use a 20moa steel rail.

    Gotta love this sport!!

    I'm a fan of the Signature ring inserts and use them to gain elevation in several rifles.
    One little tip I have to help them grip (I had a scope slip once) is to rough up the inside slick surface a bit with sandpaper. Many have mentioned scopes holding tight, but maybe I was on the low side of ring screw torque, as it was not a huge kicker (6.5-.284). Anyway, no issues after nocking off the slick finish.

    I have had no slippage issues with Burris Signature rings. The last time I used them was for mounting a big Nikon Monarch in a .338 Lapua. Again, the scope did not slip.

    I have found that the rings tend to loosen.a bit during the first 15 min after tightening the cap screws. Nowadays I come back twice after 15 and 30 min and re-tighten the screws to 30 in lbs.
