The KNS Non-Rotating Trigger/Hammer Pins are engineered for the Smith & Wesson M&P15-22, offering enhanced performance and reliability. These pins are designed to prevent movement during firing, ensuring consistent operation whether in semi-automatic or full-automatic modes. They are not compatible with standard forged aluminum AR-15 lower receivers due to their length, making them a specialized upgrade for the M&P15-22. With a maximum torque specification of 11 Inch/Lb and a suggested torque of 8 Inch/Lb, these pins provide a secure fit that enhances the overall functionality of your firearm.
