Geissele Automatics Super Duty Mod 1 13.90" Upper 5.56x45mm 1:7 M-LOK Rail with BCG and CH, Desert Dirt - Elite Performance - 08-546S

The Super Duty Mod 1 represents the pinnacle of the Super Duty platform's evolution, integrating continuous design advancements to deliver superior ergonomics and modularity while upholding its legendary balance of performance and reliability. Key to the exceptional quality and performance of this Super Duty system are the in-house cold hammer forged, chrome-lined barrel and Nanoweapon-coated Reliability Enhanced Bolt Carrier Group. Each Geissele CHF barrel and Forged Stressproof Bolt undergo rigorous High-Pressure Testing (HPT) and Magnetic Particle Inspection (MPI), ensuring unparalleled dependability and Match-grade accuracy. The Super Duty Mod 1 features a meticulously engineered gas system, which includes the bomb-proofed Super Gas Block and precisely tuned gas port sizing. When combined with the optional Geissele Super 42 braided buffer spring (available separately), these components effectively mitigate felt recoil while maintaining consistent cycling, even under adverse conditions. Enhancing its functionality, the Mod 1 is equipped with the signature Nanocoated HUXWRX flash hider-QD muzzle device, designed for seamless integration with the innovative HUXWRX FLOW series. Completing the Mod 1's upper receiver group is the robust MK16 rail with center-tab mating and stainless steel QD inserts that reinforce sling attachment points, ensuring enhanced durability and reliability. For improved operational versatility and accessibility, the Airborne charging handle enables ambidextrous use with a lower profile that minimizes the risk of snagging on gear. Together, these features establish the Super Duty Mod 1 as the benchmark for precision, durability and adaptability within contemporary firearms platforms.
