Geissele Automatics Super Duty Mod 1 Pistol 11.5″ 5.56, Desert Dirt Color
The Super Duty Mod 1 improves upon the renown Super Duty and has updated several key components to continue providing unmatched accuracy, comfort and performance.
Geissele provides the latest in weapon technology available. This 11.5” pistol chambered in 5.56mm features a nanoweapon-coated HUXWRX Flash Hider-QD installed on our 11.5” Manganese Phosphate coated, Cold Hammer Forged, Chrome Lined, 1-7 twist barrel. Geissele barrels are High-Pressure Tested (HPT) and Magnetic Particle Inspected (MPI). The Geissele length gas system and Geissele Super Compact Gas Block (with bomb-proof installation) ensure reliability and optimal performance in extreme conditions and heavy use.
At your fingertip and purpose-built for precision is the SSA-E X with Lightning Bow trigger. The 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. Our Nanoweapon-coated carrier features a properly torqued and staked, Chrome Lined, Nanocoated 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 features extended upper rails, providing greater stability and dramatically increasing feeding reliability.
The Reliability Enhanced Bolt Carrier Group comes with the Geissele Stressproof 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 10.5” 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 is renowned by operators for their performance and comfort. An Airborne Charging Handle ensures smooth and reliable operation.

Although I have not yet taken the rifle out, The customer service with Rooftop Defence is one of the best. I placed my order at 2:57 CT and even with it being so close to their cut off for same day shipping, it was shipped and I got the tracking info not long after leaving their website. My FFL recieved the rifle 2 days later. These guys could give even chik-fil-a’s customer service a run for their money.

Solid as a rock. The only thing I changed was the muzzle device. This thing drew a crowd at the gun shop when it was brought out. The ramen was a hit too. Ordered Thursday evening and was shipped Friday morning. Great gun but even better customer service from rooftop.
