Geissele Automatics Super Duty Mod 1 13.90" Upper 5.56x45mm 1:7 M-LOK Rail with BCG and CH, Black - Tactical Excellence - 08-546B

The Super Duty Mod 1 represents the latest advancement in the Super Duty platform, embodying continuous design refinement to deliver superior ergonomics and modularity while upholding its renowned balance of performance and reliability. At its core, the Mod 1 is equipped with an in-house cold hammer forged, chrome-lined barrel and a Nanoweapon-coated Reliability Enhanced Bolt Carrier Group (REBCG). Both the 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. This platform boasts a meticulously tuned gas system, featuring the bomb-proofed Super Gas Block and precisely calibrated gas port sizing. When paired with the optional Geissele Super 42 braided buffer spring (available separately), these components effectively minimize felt recoil while maintaining consistent cycling, even in adverse conditions. The Mod 1 is complemented by the signature Nanocoated HUXWRX flash hider-QD muzzle device, designed for seamless integration with the innovative HUXWRX FLOW series. Enhancing functionality, the upper receiver group includes the robust MK16 rail with center-tab mating and stainless steel QD inserts, reinforcing sling attachment points for enhanced durability. For enhanced operational versatility and accessibility, the Airborne charging handle enables ambidextrous use with a low-profile design that reduces the risk of snagging on gear. Together, these features establish the Super Duty Mod 1 as a benchmark in precision, durability and adaptability within modern firearms platforms.
