This precision rifle action integrates cutting-edge technology and materials to offer superior performance in a lightweight package. Weighing in at just 24.0 ounces, the anTi X represents the pinnacle of engineering designed to push the limits of precision shooting.

Superior Materials and Design The anTi X action is crafted from pre-hardened 416R stainless steel, providing a robust foundation that withstands the rigors of heavy use. The receiver is treated with a nitride finish enhancing its resistance to wear and corrosion, crucial for maintaining long-term reliability and performance.

  • Bolt Construction: The bolt is made from one piece of 4340 chrome moly steel, ensuring strength and providing guaranteed headspace accuracy of +/- .001″. This precision guarantees consistent performance essential for precision shooting.
  • Weight Reduction Innovations: The X-Deep anTi Fluting on the bolt not only reduces weight but also helps in cooling faster during repeated firing, maintaining the action’s performance under stress.

Advanced Features for Enhanced Performance

  • Integral Scope Mounts and Recoil Lug: Features a 20 MOA integral rail that provides a solid platform for long-range optics, essential for achieving precision at extended distances. The integral recoil lug is crucial for absorbing the recoil and maintaining zero.
  • Mini-16 Extractor and Plunger Ejector: These features ensure reliable cartridge extraction and ejection, improving the smoothness and reliability of the bolt cycling, crucial during rapid firing sequences in competitive scenarios.

Customization and Compatibility

  • Magazine Compatibility: Designed to work with hinged floorplates and center-feed detachable magazines, the action is versatile and adaptable to various shooting disciplines. The .308 version specifically supports AICS/AW magazine cuts, offering flexibility for those preferring detachable magazines.
