The GEISSELE AUTOMATICS Super Duty Rifle features the latest in weapon technology available exclusively from Geissele Automatics. This 16" rifle chambered in 5.56mm features a Nanoweapon coated Surefire Closed-Tine Warcomp mounted to an in-house 16" Mag Phosphated Cold Hammer Forge, Chrome Lined, 1-7 twist Geissele barrel. Their barrels are precision machined and cold hammer forged utilizing the highest quality materials at their state of the art facility in North Wales, PA. The Geissele Length gas system and Geissele Super Compact Gas Block (with bomb-proof installation) ensures reliability and optimal performance in extreme conditions and heavy use.

Exclusive to the Super Duty 16" Rifle is the brand new SSA-E X with Lightning Bow trigger. This nanocoated, two-stage trigger features a wide body and bow shape that finds the perfect balance between a classic M4 trigger and a flat body trigger. At the heart of this rifle is the Geissele REBCG (Reliability Enhanced Bolt Carrier Group). This Nanoweapon coated BCG is machined from mil-spec 8620 steel, with a properly torqued and staked, chrome lined gas key. The Cam Pin is machined from advanced, medical steel known as H13 which is also coated with Nanoweapon for maximum corrosion and wear resistance. The REBCG also features extended upper rails, providing greater stability and dramatically increasing feeding reliability.

The REBCG comes with the Geissele Stressproof Bolt. Made from Carpenter 158+, directly developed with Carpenter Steel metallurgists to create a material that is cleaner and has less impurities. This makes their Stressproof bolt stronger and more fatigue resistant. The Geissele Stressproof bolt is also forged, not machined from barstock. This allows us to optimize the grain structure of the steel to yield a bolt capable of 5 times the life of a mil-spec bolt. Each bolt is rigorously inspected, high pressure tested, mag particle inspected and Nanoweapon coated.

The Super Duty lower is precision machined from 7075-T6 aluminum and features Geissele's Ultra Duty Lower Parts Kit featuring their Ambidextrous Super Configurable safety and Ultra Precision trigger guard. A high quality mil-spec Geissele Buffer Tube with a Super-42 in H2 buffer ensures this rifle is properly tuned out of the box.

Rounding up the package is a 15" MK16 Super Modular Rail, that mates to the Super Duty Upper Receiver via a center aligning tab that removes any chance of rail rotation. The MK16 family of rails are renowned by operators for their performance and comfort. An Airborne Charging Handle, ensure smooth and reliable operation.

A Geissele Grip and a B5 Systems Enhanced Sopmod Stock finalizes this high-end rifle that offers the user unmatched accuracy and performance.
