Burris 420588 Signature Zee Rings 30mm Medium Height Matte Black

The Burris Signature Zee Rings deliver precision scope mounting with integrated stress relief technology that protects expensive optics from ring damage. These 30mm medium-height rings feature the patented Pos-Align offset inserts that eliminate scope stress while ensuring perfect alignment between ring halves.

What Makes This Different

Unlike standard scope rings that can stress and damage scope tubes during installation, the Signature Zee design incorporates Pos-Align inserts that compensate for manufacturing tolerances in both rings and scope rails. The four-screw cap design distributes clamping force evenly across the scope tube, while the matte black finish resists glare and corrosion. These rings mount directly to Weaver-style bases without requiring separate mounting screws.

Key Features

• Patented Pos-Align inserts prevent scope tube stress and damage
• 30mm tube diameter accommodates modern tactical and hunting scopes
• Medium height (0.5 inch) provides clearance for standard objectives up to 50mm
• Four-screw cap design ensures even pressure distribution
• Matte black anodized finish eliminates reflective glare
• Fits standard Weaver and Picatinny rail systems
• Includes multiple Pos-Align insert thicknesses for precise adjustment

The Signature Zee rings excel in demanding applications where scope reliability cannot be compromised. Competition shooters rely on the stress-free mounting to maintain zero through extended shooting sessions, while hunters appreciate the secure hold that withstands heavy recoil from magnum cartridges. The corrosion-resistant finish performs consistently in harsh weather conditions, from desert heat to mountain snow.
