Burris 420581 Signature Rings 30mm High Matte Black Scope Mounts

The Burris 420581 Signature Rings deliver precision mounting for 30mm scopes with their high-profile design that clears larger objective lenses and tactical accessories. These matte black rings feature Burris's proven clamping system that maintains zero through thousands of rounds while protecting expensive optics from mounting damage.

What Makes This Different

Unlike standard rings that rely on basic compression, the Signature series incorporates Pos-Align offset inserts that correct scope misalignment without lapping. The four-screw cap design distributes clamping force evenly across the scope tube, preventing the ring marks and optical distortion common with cheaper alternatives. High-grade steel construction handles magnum recoil while the matte finish eliminates glare that compromises shooting positions.

Key Features

• 30mm tube diameter with high-profile clearance for 50mm+ objective lenses
• Pos-Align inserts included for windage and elevation correction without lapping
• Four-screw cap design distributes 15 inch-pounds torque evenly
• Matte black finish reduces light reflection and scope glint
• Precision-machined steel construction handles magnum cartridge recoil
• Compatible with Weaver and Picatinny rail systems
• Self-centering design prevents scope tube damage during installation

Field testing shows these rings maintain point of impact through temperature extremes and heavy recoil cycles. The high mount height accommodates tactical scopes with large turrets while providing proper cheek weld on standard hunting rifles. Competition shooters rely on the consistent return to zero after scope removal, while hunters appreciate the corrosion resistance during extended outdoor exposure.
