[QUOTE="bruce_ventura, post: 701352, member: 34084"] I recall that 30 mm Signature rings include two pairs of .010" offset inserts. Using both offset inserts will provide up to about 17 MOA of elevation bias (for rings separated by 4"). The set in the back raise the scope, while the set in the front lower it. The 1" Signature rings come with no offset inserts, but i recall that the kit includes both .010" and .020" offset inserts. If so, then they will allow up to about 26 MOA of elevation bias. Does your scope have 35 MOA or +/- 35 MOA of adjustment? If its only 35 (+/- 17.5), then you will need to shim your base as well to get the 200 yd zero at a scope elevation of 0-2 MOA from the limit of adjustment (the extreme bullet down limit). This would require an accurate boresight collimator, or a lot of time shooting at the range. You should also reduce your ring separation to increase the elevation bias available from the Burris rings. If its +/- 35 MOA, then just use both .010 offset inserts to get 17 MOA of bias. Then you will have plenty of up adjustment for a 1,000 yd shot. [/QUOTE]
