Burris Signature ring inserts for 30mm

[bsekf]

I like the Burris Signature rings because of the inserts and the ability to adjust the POI with the inserts. It appears the 30mm rings only come with a 0 and +/- 5 MOA insert. Unlike the 1 inch which comes with 0,+/- 5, 10 and 20 MOA inserts. Is that correct?

Correct

False. I have 20moa built into my 30's. They may be sold separately, but they are available.

 

[savageshooter86]

I don't think that is so. My set came with 0 and 10 inserts. Burris told me they did not make other sizes for the 30mm. Only the 1" have the other insert sizes

 

[ryguy00]

Maybe they discontinued them. I know for a fact I put them into my 30's with my Nightforce to stretch out my 308 chasing prairie dogs. I bought them a long time ago and have them in both 1" and 30mm. I'll post some pictures when I get home. Or maybe we're confused on the same thing. +10 rear combined with -10 front gets you 20

Or maybe I need more coffee. The more I think about it, the more I think that's what I did. -10 combined with +10 to get 20. I did it at the prairie dog hunt last year and I'm not home to look in person right now. I think you are indeed correct. My apologies.

Burris 30mm Sigs come with 2 pr. of +/- 0 and +/- 10 inserts, yielding up to 20 MOA external elevation, but they don't sell optional inserts. The 1" rings just come with 2 sets of +/- 0 inserts and sell kits of +/- 5, 10 and 20 inserts and also sell them in single pairs (5, 10 and 20 MOA.) No 5 or 20's are available for the 30mm rings. To me, that defies explanation.

I believe the ring spacing is between 3.4"-3.6" (it's been awhile since I looked it up) to achieve the desired benefit from the ring inserts.

Yes, 3.6" is the magic number for ring spacing to make the elevation change in thousandths equal to MOA.
