The TruFire Hardcore 2.0 Buckle Foldback is an improved and more compact version of the original Hardcore Release. This new design is approximately 30% smaller for a better fit and feel in your hand. The open hook design allows for quick and easy attachment to your "D" loop without taking your eyes off your game. The Tru-Center Technology uses a self-centering knuckle to eliminate string torque while offering a comfortable, contact point with your face. The original hook design has been improved with an ultra-durable Nickle Boron coating to reduce friction and improve accuracy. Customize the fit precisely to your preference with the 360-degree rotatable head with length adjustment that allows almost a full inch of adjustment. Micro adjust travel and pressure adjustment allows you to set the trigger exactly to the settings you prefer. In addition, the Hardcore 2.0 features a new interchangeable trigger system that allows you to swap from the original swept-back trigger to a curved trigger, a knurled post, or a 2-finger design, allowing you to find the most comfortable shooting position. The ultra-comfortable black leather buckle strap features TruFire's patented FoldBack design that allows users to fold the release out of the way when not in use. TruFire's TrapTab with its hallmark TruFire arrowhead triangle design prevents the strap from pulling back through the buckle making light work of putting the release on and eliminating the need for a third hand during application.
