CNC-machined in the USA from lightweight, aircraft-grade 6061-T6 aluminum with a non-reflective matte Type III hardcoat anodized black finish, it features a Picatinny-type rail (MIL-STD-1913) with standard multi-slot cross-slot spacing compatible with both Picatinny and Weaver-style rings. Flat 0 MOA profile provides optimal mounting height and eye relief alignment. Includes mounting hardware; recommended torque is 35 in-lbs for crossbolt screws and 15 in-lbs for cap screws. 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.
