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 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 H2 buffer ensures this rifle is properly tuned out of the box.
Rounding up the package is a 15” 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 are renowned by operators for their performance and comfort. An Airborne Charging Handle, ensure smooth and reliable operation.
A Geissele Rifle Grip and a B5 Systems Enhanced Sopmod Stock finalizes this high-end rifle that offers the user unmatched accuracy and performance.
