The Geissele Super Duty Upper features the latest in weapon technology available exclusively from Geissele Automatics. This complete upper chambered in 5.56mm features a Nanoweapon coated Surefire Closed-Tine Flash Hider mounted to a Mag Phosphated, CHF, Chrome Lined 1-7 twist barrel. Geissele barrels are precision machined and cold hammer forged utilizing the highest quality materials at their state of the art facility. The carbine length gas tube and Geissele Super Compact Gas Block with bomb-proof installation ensures reliability and optimal performance in extreme conditions.
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 the Geissele Stressproof bolt stronger and more fatigue resistant. The Geissele Stressproof bolt is also forged, not machined from barstock. This allows Geissele machinists 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.
All of these technologies and advancements combine to bring to market a true next-gen upper for the AR-15 platform. The Super Duty Complete Upper from Geissele Automatics offers unmatched performance, accuracy and reliability.
