The KNS Bolt Catch Retaining Pin for AR15/M16 is an essential internal component designed to secure the bolt catch assembly, preventing unintended separation during operation. This precision-engineered retaining pin is ideal for both law enforcement and civilian shooters who require reliability during sustained fire and tactical use.

Manufactured by KNS Precision, this retaining pin is made from hardened steel, ensuring durability and resistance to wear from repeated charging and bolt closure cycles.
