The revolutionary Signature design guarantees consistent accuracy, tremendous gripping power, and stress-free mounting for your scope. These steel rings feature a pivoting synthetic insert that increases the scope-to-ring mounting surface while safeguarding the finish of your scope. For those needing additional adjustment, Pos-Align Offset Inserts can be purchased separately to correct any misalignment of receiver holes or rings and provide extra windage and elevation adjustment. The Signature design rings come in various sizes: 1" rings include two sets of "0" (zero) inserts. 30 mm rings include two sets of "0" (zero) inserts along with two sets of +10 and –10 inserts. 34 mm rings include two sets of "0" (zero) inserts, one set of +10 and –10, and one set of +20 and –20 inserts. Signature rings feature synthetic pivoting inserts that enhance the scope-to-ring surface area, ensuring consistent accuracy and greater gripping power while allowing for scratch-free and stress-free mounting. The mounting hardware is included to make installation a breeze. For additional precision, Signature rings can be used with Burris Pos-Align offset inserts, which are available separately. These inserts replace the standard ones and allow the scope tube to be moved within the ring itself, rather than relying solely on the scope's windage and elevation adjustments. The offset inserts are available in .005", .010", and .020" offset distances. Each set of offset inserts moves the scope tube by the specified amount, allowing for precise adjustments. For example, a .005" offset insert will shift the scope tube .005" towards the thinner of the two inserts. You can use these inserts in the front ring, rear ring, or both, and in any combination necessary to achieve the desired adjustment. This flexibility ensures that you can fine-tune your scope's alignment for both windage and elevation. With these features, the Signature rings provide a reliable and versatile solution for scope mounting, ensuring your setup is precise and secure.
