The KNS Bolt Catch Retaining Pin for AR15/M16 is a critical internal component designed to secure the bolt catch assembly and prevent unintended separation during operation. This precision-engineered retaining pin serves both law enforcement and civilian shooters who demand reliability under sustained fire and tactical use. Whether running duty builds, competition setups, or field-grade carbines, a quality bolt catch retaining pin is non-negotiable for safe, consistent function.

KNS Precision manufactures this retaining pin to exacting tolerances, ensuring a snug fit that eliminates wobble and play within the bolt catch assembly. The hardened steel construction resists wear from repeated charging and bolt closure cycles, maintaining dimensional stability across thousands of rounds. Black finish protects against corrosion and reduces light reflection, while the compact 1.95-inch length and minimal 0.05-pound weight integrate seamlessly into the receiver without adding bulk or affecting balance. Proper retention of this pin is essential for safe bolt catch function and prevents potential safety hazards during operation.

This retaining pin is compatible with standard AR15 and M16 platforms, making it ideal for drop-in replacement, upper receiver assembly, or maintenance and repair workflows. Armorers, gunsmiths, and field technicians regularly stock this component as part of preventive maintenance programs to eliminate wear-induced pin drift. Installation requires only basic AR platform knowledge and standard takedown procedures—no special tools necessary. For anyone building or maintaining an AR15 or M16 variant, sourcing genuine KNS Precision components ensures long-term reliability and peace of mind.
