The Geissele Super Duty MOD1 Pistol in 11.5" 5.56MM combines Geissele's proven Super Duty platform with updated ergonomics, modularity, and performance-focused components. Finished in Desert Dirt Color (DDC), this compact 5.56 pistol features an 11.5" cold hammer forged, chrome-lined barrel with a 1:7 twist, a Geissele Stressproof Bolt®, and a precisely balanced carbine-length gas system.

The MOD1 configuration includes a HUXWRX Flash Hider-QD 556 for compatibility with HUXWRX FLOW series suppressors, along with a 10.5" MK16 rail with Geissele Center Tab. An SSA-E X® two-stage trigger with Lightning Bow® provides a refined trigger interface, while the Super Configurable Safety, Airborne Charging Handle, Maritime Bolt Catch, and checkered magazine release provide purpose-driven controls.
