Geissele Super Duty MOD1 5.56mm NATO 12.5" Barrel NO Mag DDC
The Super Duty Mod1 Pistol improves upon the renowned Geissele Super Duty with the addition of a HUXWRX Flash Hider-QD 556 suppressor-ready muzzle device, an updated MK16 Super Modular Rail with press-fit stainless steel Quick Disconnect (QD) inserts, and an A17 Grip that presents a more ergonomic grip angle. The SD Mod1 updates several key components that ensure this high-end firearm will continue to offer the user unmatched accuracy, comfort, and performance.
Geissele provides the latest in weapon technology available. This pistol chambered in 5.56mm features a nanoweapon-coated HUXWRX Flash Hider-QD muzzle device mounted to an in-house 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-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 (BCG). Their 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. Made from Carpenter 158+, directly developed with Carpenter Steel metallurgists to create a material that is cleaner and has fewer 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 H3 buffer ensures this rifle is properly tuned out of the box.
A Geissele Quick Disconnect (QD) Sling Mount Endplate allows for fast interfacing of slings quipped with QD pushbutton mounts to the lower receiver. This rugged and reliable attachment point is machined from Stainless Steel that is finished in Black Nitride and staked per MIL STD. Rounding up the package is a 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.

The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
The 5.56X45mm NATO cartridge was designed by James Sullivan, a member of Eugene Stoner's engineering team that developed both the M16 rifle and its original cartridge. The 5.56X45mm NATO was adopted by the U.S. military in 1964 and by NATO in 1980. With bullet diameter of .224-inch, the original M193 military cartridge used a 55-grain bullet at 3250 fps; the current M855A1 cartridge, developed by FN, uses a 62.5-grain bullet at 3020 fps, offering greater range and better penetration. The civilian version of the 5.56X45mm is 223 Remington; the cartridges are dimensionally identical but military chamber dimensions and specifications for military brass are different. It is considered safe to use 223 Remington ammo in a 5.56X45MM NATO chamber, but not a good idea to use 5.56X45mm ammo in a rifle specifically chambered for the 223 Remington. Although the stopping power of .22-caliber bullets remains controversial the 5.56X45mm has served well in now multiple generations of M16 rifles.
