Geissele Super Duty Mod1: Purpose-Built Performance
The Super Duty Mod1 represents a significant evolution in modern rifle design, building on Geissele's proven Super Duty platform with thoughtful upgrades that enhance both capability and usability.
Barrel and Muzzle System
The heart of this rifle is a 14.5" barrel—a practical length that balances velocity and maneuverability. The barrel features:
- Cold Hammer Forged construction with Manganese Phosphate coating for durability
- Chrome lined for extended service life
- 1-7" twist rate optimized for modern 5.56mm ammunition
- HUXWRX Flash Hider-QD muzzle device with Nano weapon coating, ready for suppressor mounting
Trigger and Controls
The SSA-E X trigger with Lightning Bow delivers the crisp, predictable break that Geissele is known for. The lower receiver features:
- Ambidextrous Super Configurable safety for left and right-handed shooters
- Ultra Precision trigger guard machined as part of the lower
- A17 Grip with improved ergonomic angle for natural hand positioning
- Airborne Charging Handle for smooth, reliable operation
Rail System and Mounting
The 13.5" MK16 Super Modular Rail incorporates press-fit stainless steel Quick Disconnect inserts, allowing you to mount accessories exactly where you need them. The QD Sling Mount Endplate enables rapid sling attachment and detachment using standard pushbutton QD mounts.
Receiver and Internal Components
The lower receiver is precision machined from 7075-T6 aluminum and includes Geissele's Ultra Duty Lower Parts Kit. The upper features an Enhanced Bolt Carrier Group tuned for reliability. A Super-42 buffer in H2 configuration paired with a mil-spec Geissele Buffer Tube ensures the rifle cycles smoothly out of the box.
Stock and Ergonomics
The B5 Systems Enhanced Sopmod Stock provides a solid cheekweld and comfortable length of pull, completing a rifle that's ready for training, competition, or duty use.
This is a rifle built by shooters, for shooters—no compromises.
