This is a precision replacement screw for A2-style match grade rear sight assemblies. The windage knob screw secures the windage adjustment mechanism and interfaces directly with the rear sight base. It's engineered to maintain consistent zero and repeatable adjustments across multiple shooting sessions. Made from steel with a black finish, this screw handles the mechanical demands of precision long-range shooting without degradation.
This screw is designed specifically for match grade rear sight systems where repeatability matters. The slotted head allows for precise torque application without stripping, and the partially threaded design ensures the screw seats consistently in the windage assembly. The steel construction handles repeated adjustment cycles without wear or play.
This windage knob screw fits A2-style match grade rear sight assemblies. It serves as a direct replacement component for existing systems or as a spare for shooters who maintain multiple rifles. Verify your rear sight base matches the A2-style match grade pattern before ordering.
Steel with a black finish provides corrosion resistance and longevity in field conditions. The material choice supports the precision requirements of match grade sight systems without requiring special maintenance or coating care.
Follow safe handling and manufacturer instructions. Ensure compatibility with all applicable federal, state, and local laws.
