The Fierce Firearms 30mm Medium Scope Rings (MPN: FSR-30M / UPC: 853418908624) provide a rock-solid, ultra-precise optic mounting foundation engineered to withstand the punishing recoil of magnum hunting calibers and long-range precision rifles. Precision CNC-machined from high-grade 7075 aircraft aluminum, these rings deliver the high tensile strength of steel at a fraction of the weight, ensuring your scope stays in alignment in the backcountry.
Engineered to clamp seamlessly to standard Mil-Spec 1913 Picatinny rails and Weaver-style bases, the FSR-30M medium height profile (.885" height) provides ideal clearance for 30mm maintube scopes with objective lenses up to 50mm while maintaining a natural, comfortable cheek weld.
7075-T6 Billet Aluminum Construction: Machined to exacting tolerances from aerospace-grade 7075 aluminum, offering significantly higher yield strength than standard 6061 alloy.
Universal Rail Compatibility: Designed to fit standard Mil-Spec 1913 Picatinny and Weaver-style rail sections with a cross-bolt locking interface.
No-Lapping Precision Fit: Precision bore alignment minimizes stress and pinching on your scope tube, eliminating the need for ring lapping out of the box.
Type III Hard-Coat Anodized Finish: Non-reflective matte black finish delivers exceptional resistance to corrosion, scratches, and harsh environmental exposure.
High-Torque Hardware: Fitted with heavy-duty Torx screws with fine thread pitch for secure, even clamping pressure across your optic maintube.
Medium Profile Clearance: Offers the ideal height for clearance over medium and heavy barrel contours while keeping the optic bore-axis low and aligned.
