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 headspace tolerance of +/- .001a ^2 action to action, allowing the use of shoulder pre-fit barrels. 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, to the same tolerances, and utilizes the same shouldered re-fit barrels as the Ruckus and Anti Rec Mfg: Defiance Machine
