Defiance anTi X: Revolutionizing Precision with Lightweight Design and Advanced Features


Defiance is synonymous with innovation and precision in the firearm industry, continually setting new standards with advanced designs. The latest breakthrough, the anTi X, exemplifies this commitment by combining ultra-lightweight construction with uncompromised performance. This model is designed for enthusiasts who demand the best in terms of reliability, durability, and precision.

Ultra-Lightweight Build and Superior Materials

The anTi X is engineered to be as light as possible without sacrificing strength or performance. Weighing approximately 23 ounces, this action is one of the lightest on the market, ideal for those who value mobility and ease of handling. The use of pre-hardened 416R stainless steel for the receiver and 4340 chrome moly steel for the bolt ensures a blend of lightweight construction with exceptional durability.

Key Specifications:

  • Weight: Starts at 23 oz for the short action model.
  • Materials: Pre-hardened aircraft-certified 416 stainless steel and 4340 chrome moly.
  • Action Types: Available in short, medium, XM, and long actions, catering to various shooting disciplines and preferences.

Advanced Design Features

The anTi X boasts several features that enhance its functionality and performance:

  • Integral Scope Mounts and Recoil Lug: Ensures a secure and stable platform for precision shooting.
  • Guaranteed Headspace Measurement: Offers accuracy comparable to Defiance’s other renowned models such as Ruckus and Renegade.
  • Innovative Fluting and Bolt Design: The deep anTi fluting and recessed bolt nose enhance operational smoothness and reduce overall weight.

Detailed Features:

  • Headspace Tolerance: Guaranteed to be within +/- .001″.
  • Rail Options: 0 or 20 MOA integral rail, skeletonized for reduced weight.
  • Bolt Face Diameters: Ranging from .390" to .595", accommodating a variety of calibers.

Precision Engineering

Defiance’s commitment to precision is evident in every aspect of the anTi X. The receiver and bolt are machined from single pieces of pre-hardened steel, ensuring consistent quality and reliability. The wire EDM-cut, full-length lug ways and anti-bind features result in a bolt operation that is both smooth and reliable.

Manufacturing Excellence:

  • One-Piece Construction: Both the bolt and receiver are crafted from single pieces of steel, enhancing structural integrity.
  • Smooth Bolt Cycling: Primary extraction design significantly increases initial extraction force, ensuring smooth operation under various conditions.

Comprehensive Accessories Included

The anTi X comes equipped with all necessary components to ensure peak performance right out of the box:

  • Complete Action Assembly: Includes the stainless-steel receiver, one-piece bolt, handle/knob, and more.
  • Customization Options: Features such as the Mini-16 extractor, hollow anTi bolt knob, and fluted firing pin are designed for both aesthetic appeal and functional superiority.


The Defiance anTi X is a pinnacle of firearm engineering, blending state-of-the-art materials with innovative manufacturing techniques to offer shooters an ultra-lightweight, highly reliable action. Whether for competitive shooting or hunting, the anTi X provides an unmatched combination of performance, precision, and portability, making it a top choice for discerning firearms enthusiasts.
