As Defiance has grown it has gained more equipment and more abilities. The already popular Tenacity has been updated with these advances to now come standard with an integral recoil lug. With the integral recoil lug and precision machined bolt the Tenacity guarantees a tolerance of +/- .001 action to action.

Since some shooters and hunters don’t always need custom options, Defiance has introduced a well-designed, precision rifle action at a great value. The Tenacity is machined from the same steels and to the same tolerances as the Rebel and Deviant. Limited options (see below), but a versatile design that delivers either on the range or deep in the wilderness.
