The Geissele Super Duty Upper (Complete) features the latest in weapon technology available exclusively from Geissele Automatics. This 11.5” complete upper chambered in 5.56mm features a Nanoweapon coated Surefire Closed-Tine Warcomp mounted to an 11.5” Mag Phosphated, CHF, Chrome Lined 1-7 twist barrel. The barrels are precision machined and cold hammer forged utilizing the highest quality materials at a state-of-the-art facility in North Wales, PA. The carbine length gas tube and Geissele Super Compact Gas Block with bomb-proof installation ensures reliability and optimal performance in extreme conditions.

Included is a brand new, 10.5” Super Modular Rail MK16 that mates to the upper via a center aligning tab removing any chance of rail rotation. This rail is a variant of the 13.5” SMR MK16, currently fielded by USASOC and renowned by operators for their performance and comfort.

Also included is the Geissele REBCG, Reliability Enhanced Bolt Carrier Group. This Nanoweapon coated BCG is machined from mil-spec 8620 steel, with a properly torqued and staked, chrome-lined gas key. The Cam Pin is machined from advanced, medical steel known as H13 which is also coated with Nanoweapon for maximum corrosion and wear resistance. The REBCG also features extended upper rails, providing greater stability and dramatically increasing feeding reliability.

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 fewer impurities. This makes their Stressproof bolt stronger and more fatigue resistant. The Geissele Stressproof bolt is also forged, not machined from bar stock. 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.
