RECOMMENDED FOR YOU
- The Super Duty MOD1 is the current evolution of the Super Duty platform, incorporating continuous design development to provide superior ergonomics and modularity while maintaining the legendary balance of performance and reliability. Foundational to the renowned quality and performance of this Super Duty system is the in-house produced Cold Hammer Forged, chrome-lined barrel and Nanoweapon-coated Reliability Enhanced Bolt Carrier Group. Both the Geissele CHF barrel and Forged Stressproof Bolt are High-Pressure Tested (HPT) and Magnetic Particle Inspected (MPI), and work in concert to achieve unmatched dependability with match-grade accuracy. The Super Duty features a precisely balanced gas system, including the bomb-proofed Super Gas Block, fine-tuned gas port sizing and Super 42 braided buffer spring. These purposefully selected components minimize felt recoil while maintaining reliable cycling, even in adverse conditions. The MOD1 features the signature Nanocoated HUXWRX Flash Hider-QD muzzle device, offering seamless compatibility with the innovative HUXWRX FLOW series.
- Rounding out the MOD1, the well-vetted center-tab mated MK16 rail and SB Tactical SBA3 brace uphold the exceptional ergonomics the Super Duty is known for. The MOD1 enhances handling with the modernized A17 grip, and improves on modularity with the incorporation of the Geissele Quick Disconnect (QD) Sling Mount Endplate and stainless steel QD inserts on the MK16 rail. Manufactured with confidence and without compromise, the Super Duty MOD1 adds value to the platform while continuing the reputation for excellence.
