Geissele Automatics Super Duty MOD1, SBR, 11.5″, 5.56mm, DDC

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 Compact 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.
