Geissele Super Duty MOD1 16" 5.56 NATO AR-15 Rifle
The Geissele Super Duty MOD1 represents the latest evolution of Geissele's flagship duty rifle platform. Built around premium American-made components and engineered for hard use, the MOD1 combines outstanding reliability, refined ergonomics, and exceptional accuracy for defensive, professional, and recreational shooters alike.
At the heart of the rifle is a 16-inch cold hammer forged barrel chambered in 5.56 NATO with a 1:7 twist rate. Paired with Geissele's proprietary gas system, the rifle delivers smooth recoil impulse, consistent reliability, and excellent performance across a wide range of ammunition.
Duty-Ready Performance
Every Super Duty MOD1 is built to exceed military specifications using premium materials and meticulous manufacturing processes. The cold hammer forged barrel offers exceptional longevity while the Geissele-length gas system helps reduce recoil, improve reliability, and extend component life.
Precision Geissele Trigger
The rifle comes equipped with the renowned SSA-E X trigger featuring the Lightning Bow. This two-stage trigger provides a crisp, predictable break with excellent control for precision shooting while maintaining the reliability expected from a duty rifle.
Premium Controls & Furniture
The Super Duty MOD1 includes numerous premium upgrades including the Airborne Charging Handle, Geissele A17 pistol grip, Super 42 braided buffer spring, and a B5 Enhanced SOPMOD stock. Together, these components deliver improved ergonomics, smoother operation, and enhanced shooter comfort.
Free-Float MK16 Handguard
The 15-inch Geissele SMR MK16 free-float rail provides ample space for optics, lights, lasers, bipods, and other accessories while maximizing barrel accuracy. The Geissele Center Tab mounting system enhances rigidity and helps maintain zero under demanding conditions.
Optimized Muzzle System
A factory-installed HUXWRX QD 5.56 flash hider offers excellent flash suppression while providing compatibility with HUXWRX quick-detach suppressor systems, making the rifle suppressor-ready out of the box.
