Hardcore’s were designed to be the ultimate hook (single jaw) release with more features than any other. For starters, the HARDCORE has a self centering knuckle located behind the main body which eliminates side to side torque which is a major design flaw with other hook style releases. The body will actually pivot left or right for a total of 20 degrees to compensate for varying anchor point positions. Once attached to a bow, the loop or serving will line up straight with the centerline of the release which allows for a perfect shot every time. The solid steel jaw automatically closes when you depress the trigger and when set with minimal travel, trigger pressure is a mere 4 ounces. Swept back trigger. This release is the ultimate for hardcore hunters as well as serious tournament archers. As always, proudly made in the USA.
