As Defiance continues to innovate and find new ways to better serve our customers, we have pushed the envelope again. The anTi X is an ultra-lightweight action with integral scope mounts and recoil lug that shares the same guaranteed head-space measurement as our Ruckus, Tenacity, and anTi custom precision rifle actions. Using pre-hardened 416R stainless for the receiver and a 4340 chrome moly bolt, gives customers the smoothness, reliability and longevity that they have come to expect from Defiance. Innovative weight reduction. Premium Materials. No compromises. All material pre-hardened prior to machining to prevent changing tolerances during heat treat. Bolt machined from one piece Mfg: Defiance Machine
