The Geissele Automatics Super Duty Mod 1 AR Pistol, chambered in 300 Blackout, represents a continuous evolution in firearms design. This platform integrates advanced components to deliver superior ergonomics and modularity while maintaining Geissele’s established benchmark for performance and system reliability. Engineered for precision and operational consistency, the Super Duty Mod 1 is a formidable and adaptable AR pistol.
Key Features
Precision Barrel System
The 8-inch cold hammer forged, chrome-lined barrel provides exceptional durability and bore longevity, crucial for consistent projectile velocity and accuracy. This barrel features a threaded muzzle, enabling the integration of various muzzle devices or suppressors to mitigate muzzle flash and report.
Advanced Trigger Integration
Central to the Super Duty Mod 1’s operational precision is the Geissele SSA-E X two-stage trigger with Lightning Bow. This trigger delivers a crisp, predictable break and a positive reset, facilitating rapid and accurate follow-up shots. Its two-stage design optimizes control for both deliberate precision engagements and dynamic close-quarters operation.
Optimized Recoil Management
The proprietary Geissele Phased Array gas system is engineered to regulate cycling pressure efficiently, ensuring smooth and consistent operation across varying ammunition types. This is complemented by a Geissele braided buffer spring, designed to further reduce felt recoil and mitigate bolt bounce, enhancing the shooter’s ability to maintain a sight picture.
Enhanced Ergonomics and Control
The Super Duty Mod 1 is configured with components selected to enhance user interface and control. It features a Synthetic SB Tactical SBA3 Brace for stable shouldering, a Geissele A17 grip designed for positive hand placement, and an Airborne charging handle for ambidextrous manipulation. The Geissele SMR MK16 handguard, featuring a robust center tab, provides a stable accessory mounting platform. A configurable safety selector allows for user-defined operation, and a Geissele QD sling mount endplate facilitates rapid sling attachment and detachment.
