Talley Scope Mount/Ring Combo features a 30mm tube diameter and medium mount height (0.540 front / 0.646 rear centerline profile). Designed for Browning X-Bolt long action and magnum rifles (does not fit A-Bolt, A-Bolt II, or AB3 models), this 2-piece set of unitized ring-and-base structures weighs 2.50 oz and provides 20 MOA offset. Finished in black anodized, it includes scope rings and hardware to mount directly into factory receiver holes using Browning's 4-screw-per-base footprint with 6-48 Torx screws without a rail interface. Safety Note Always ensure the firearm is unloaded before installing or adjusting any optics or bases. Verify proper torque specifications during installation. Improper mounting may affect accuracy and safety.
