This Nanoweapon-coated BCG features 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 Geissele Reliability Enhanced Bolt Carrier Group also features extended upper rails, providing greater stability and dramatically increasing feeding reliability.</p><p><br></p><p>The Geissele 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 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.</p><p><br></p><p>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.</p>
