Talley Scope Mount/Ring Combo features a 30mm tube diameter and medium mount height (0.500 from receiver top to scope tube bottom). Designed for Browning X-Bolt rifles across short, long, and super short actions (does not fit A-Bolt or AB3 models), this 2-piece set of unitized ring-and-base structures weighs 2.50 oz. Finished in black anodized, it includes scope rings and hardware to mount directly into factory receiver holes using Browning's 4-screw-per-base X-Lock system 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.
