Key Features

Geissele Nanoweapon Technology

Geissele's exclusive Nanoweapon technology offers unprecedented corrosion, wear, and abrasion resistance. This coating, harder than sand and similar to synthetic diamond, rejects carbon, requires less lubrication, and simplifies cleaning, ensuring your firearm's longevity and performance.

Reliability Enhanced Bolt Carrier Group (REBCG)

The heart of the Super Duty Rifle is the REBCG. This Nanoweapon coated BCG features a chrome-lined gas key, a Cam Pin made from advanced H13 tool steel, and extended upper rails to ensure stability and reliable feeding.

Geissele Stressproof Bolt

Made from Carpenter 158+, the Geissele Stressproof Bolt was developed directly with Carpenter Steel metallurgists. This bolt is forged, not machined, from cleaner material with fewer impurities, resulting in a stronger, more fatigue-resistant bolt that is 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.

Ultra Duty Lower Parts Kit

The Super Duty Lower is precision machined from 7075-T6 aluminum and features Geissele’s Ultra Duty Lower Parts Kit, ensuring this rifle is properly tuned right out of the box. The kit features an Ambidextrous Super Configurable safety and Ultra Precision trigger guard.

Super-42 with H2 Buffer

Equipped with a high-quality mil-spec Geissele Buffer Tube with a Super-42 in H2 buffer, this rifle assures smooth and reliable operation.

MK16 Super Modular Rail

A 15” MK16 Super Modular Rail, renowned for its performance and comfort, mates to the Super Duty Upper Receiver via a center aligning tab that removes any chance of rail rotation.

Comfort and Convenience

The Airborne Charging Handle ensures smooth and reliable operation. A Geissele Grip and a B5 Systems Enhanced Sopmod Stock round out this high-end rifle, offering the user unmatched accuracy and performance.
