Super Duty® MOD1 Complete Upper, 16" Heavy Barrel, 5.56mm
Super Duty® MOD1 Complete Upper, 16" Heavy Barrel, 5.56mm
The Super Duty® MOD1 Heavy Barrel (HBAR), takes the Super Duty® platform to the next level, with a heavy profile barrel that can handle sustained rates of fire while maintaining the accuracy and reliability the Super Duty is known for.
Both the Geissele CHF Heavy 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 Forged Stressproof Bolt® is made from Carpenter 158+, directly developed with Carpenter Steel metallurgists to create a material that is cleaner and has less impurities. This makes the Stressproof Bolt® stronger and more fatigue resistant, capable of 5 times the life of a mil-spec bolt.
The Super Duty features a precisely balanced gas system, including the bomb-proofed Super Gas Block and fine-tuned gas port sizing, especially when combined with the Geissele Super 42 braided buffer spring (sold separately). These purposefully selected components minimize felt recoil while maintaining reliable cycling, even in adverse conditions. The MOD1 features the HUXWRX Flash Hider-QD muzzle device, offering seamless compatibility with the innovative HUXWRX FLOW series.
Rounding out the MOD1 complete upper receiver group, the well-vetted center-tab mated MK16 rail features stainless steel QD inserts to reinforce sling attachment. The Airborne Charging Handle provides ambidextrous use and accessibility while maintaining a lower profile to eliminate snagging on gear.
Manufactured with confidence and without compromise, the Super Duty MOD1 HBAR adds value to the platform while continuing the reputation for excellence.

What is Geissele Nanoweapon®?
Geissele Nanoweapon® (also known as Picatinny DSL) is a family of Durable Solid Lubricant coatings which was developed by ARDEC. It is available exclusively from Geissele Automatics. We continued the development of Picatinny DSL so that its level of corrosion, wear and abrasion resistance is currently unmatched among firearm coatings. Nanoweapon® is applied at low temperatures so that the underlying metallurgy of the part is unaffected by the application process. Our coating also has a surface hardness roughly equivalent to synthetic diamond. This makes Geissele Nanoweapon® harder than sand, easily rejecting carbon and making cleaning a breeze, on top of allowing the firearm to operate normally with less lubrication.
