The Rise Armament Super Sporting Trigger (SST) Don't Tread on Me Gen 2 Trigger is a high-performing, cost-effective upgrade to replace mil-spec triggers. It has a clean break with a short reset and comes with anti-walk pins for installation. The triggers are manufactured and assembled in Rise Armament's facility according to strict AS9100 aerospace requirements, which are more stringent than standard gun manufacturing requirements. They are backed by a lifetime guarantee through Rise Armament. This Gen 2 Trigger features the same mechanics of the original Don't Tread on Me Rise Armament trigger, but with an updated dynamic rattlesnake design that pays homage to the Gadsden flag with a bold new look!
