The Edge line of releases is designed with a smaller than dime sized head. Even though it has been scaled back to suit your tastes, the Edge retains the functionality and benefits you expect from Tru-Fire. The Edge release line utilizes a linear motion bearing which delivers an extremely smooth trigger feel. Pull the trigger back to open the jaws, and let up on the trigger to close the jaws. Also new on the Edge is a lockdown set screw for your length adjustment. Once you have the correct length simply tighten the set screw and the length will be locked in place. This small product innovation is a perfect example of how we continue to engineer products that will help you become a better shot. 100% American Made.
