Overview

Geissele Super Duty Mod1 Features The Geissele Super Duty Mod1 is built around a cold hammer-forged chrome-lined 14.5 heavy profile barrel with a 1-in-7 twist rate running on a mid-length gas system through a Super Compact Gas Block with a .750 gas journal and .076 gas port. The Super Duty M4 upper and Super Duty Lower mil-spec receiver set are paired with a Reliability Enhanced Bolt Carrier Group and Geissele Stressproof Bolt engineered to maintain function under sustained fire and adverse conditions. A HUXWRX QD 556 flash hider on a 1/2x28 thread pattern completes the muzzle end with a quick-detach suppressor-ready interface. The 13.5 MK16 rail with Geissele Center Tab provides a full-length rigid mounting surface for lights lasers and accessories while keeping the handguard slim and comfortable for varied shooting positions. The SSA-E X trigger with Lightning Bow delivers a crisp two-stage pull tuned for precision and rapid follow-up shots complemented by a Super Configurable Safety Selector and Ultra Duty Lower Parts Kit throughout the lower. A Super 42 buffer assembly with H2 buffer mil-spec 6-position 7075-T6 buffer tube with Geissele QD endplate B5 Systems Enhanced Sopmod Stock and Geissele A17 grip round out a lower build with no compromises. Geissele Automatics has built its reputation supplying components and complete rifles to U.S. military and law enforcement units and the Super Duty Mod1 reflects that lineage by applying the same material standards and manufacturing tolerances to a commercially available package. Every specification on this rifle traces back to a deliberate engineering decision making the Super Duty Mod1 one of the most thoroughly considered production AR platforms available.
