Let's face it, you want a short barreled rifle, and you want to run suppressed, but you do not want another tax stamp and you do not want the length that a 16" barrel gives you with the can out there pushing 20".

Unique DDC Finish: The DDC anodized finish is unique to Geissele, and showcases craftsmanship and the challenges of precision manufacturing. This finish is known for its wide variation, ranging from dull light brown to a tan to a taupe, and maybe some desert sand mixed up in there. Due to these variations and limited production runs, But, with that also comes the expectation that the color you see in the pics might not be the exact color you receive.

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 quality and performance of this Super Duty system is the Geissele made Cold Hammer Forged, chrome-lined barrel and Nanoweapon-coated Reliability Enhanced Bolt Carrier Group. Both the Geissele CHF barrel and Forged Stressproof Bolt are individually High-Pressure Tested (HPT) and Magnetic Particle Inspected (MPI), and work in concert to achieve dependability with match-grade accuracy. The Super Duty 13.9" RECCE model 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 signature Nanocoated 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 and while maintaining a lower profile to eliminate snagging on gear
Geissele's Attention to Detail: True to their reputation for over-engineering, Geissele has implemented features that go above and beyond standard specifications. The bombproof gas block installation and the dovetail rail interface are prime examples of Geissele's commitment to reliability and precision. Nanocoating is another, which is DLC coating applied to both the bolt carrier group and the flash hider for superior performance and corrosion resistance.
