Super Duty MOD1 Complete Upper | 10.3"

Geissele Super Duty MOD1 Complete Upper | 10.3" - 5.56 mm

The Super Duty MOD1 is the latest evolution of the Super Duty platform. It features continuous design refinements to deliver superior ergonomics and modularity while maintaining the legendary balance between performance and reliability.

The foundation for the Super Duty system’s renowned quality and performance is its in-house manufactured cold-forged, chrome-plated barrel and the Nanoweap-coated Reliability Enhanced Bolt Carrier Group. Both the Geissele CHF barrel and the forged, stress-relieved bolt are individually high-pressure tested (HPT) and magnetically particle inspected (MPI), and they work together to achieve unmatched reliability and precision.

The Super Duty features a precisely balanced gas system, including the bombproof Super Gas Block and finely tuned gas port sizes, particularly when combined with the Geissele Super 42 braided buffer spring (sold separately). These carefully selected components minimize perceived recoil and ensure reliable operation even under adverse conditions. The MOD1 is equipped with the signature nano-coated HUXWRX Flash Hider-QD, which is seamlessly compatible with the innovative HUXWRX FLOW series.

The proven MK16 rail with a center rail and stainless steel QD inserts for attaching the sling rounds out the MOD1 upper receiver. The Airborne charging handle allows for ambidextrous operation and accessibility and is low-profile enough to avoid snagging on gear.

The Super Duty MOD1 was developed with conviction and without compromise to enhance the platform’s value while maintaining its reputation for outstanding quality.

All of these technologies and advancements come together in the development of a new generation of uppers for the AR-15 platform.

The Super Duty Complete Upper from Geissele Automatics offers unmatched performance, precision, and reliability.
