The 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 Flash Hider mounted to an in-house 16” durable black oxide, Cold Hammer Forge, Chrome Lined, 1-7 twist Geissele barrel. Our barrels are precision machined and cold hammer forged utilizing the highest quality materials at our 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 Reliability Enhanced Bolt Carrier Group. This Nanoweapon coated BCG features a properly torqued and staked, chrome lined gas key. The Cam Pin is machined from advanced, tool steel known as H13 which is also coated with Nanoweapon for maximum corrosion and wear resistance. The Reliability Enhanced Bolt Carrier Group also features extended upper rails, providing greater stability and dramatically increasing feeding reliability.
The Reliability Enhanced Bolt Carrier Group 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 our 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 our 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 ensures 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.

What is Geissele Nanoweapon?
Geissele Nanoweapon (also known as Picatinny DSL) is a family of Durable Solid Lubricant coatings which was developed by ARDEC. It is available exclusively from Geissele Automatics. We continued the development of Picatinny DSL so that its level of corrosion, wear and abrasion resistance is currently unmatched among firearm coatings. Nanoweapon is applied at low temperatures so that the underlying metallurgy of the part is non effected by the application process. Our coating also has a surface hardness roughly equivalent to synthetic diamond. This makes Geissele Nanoweapon harder than sand, easily rejecting carbon and making cleaning a breeze, on top of allowing the firearm to operate normally with less lubrication.
What is “40mm Green”?
“40mm Green” is a particular shade of color. It is called such because the parts in this rifle are anodized in the same dye tanks as military 40mm grenade cases.
