Product Description

Built with a no-compromise approach, the Geissele Automatics Super Duty MOD1 Complete Upper Receiver Group delivers next-generation performance for AR-15 builds. This 5.56 NATO upper centers around a 13.9-inch cold hammer forged, chrome-lined barrel and a HUXWRX Flash Hider-QD muzzle device that is pinned and welded for a durable, ready-to-run configuration. A mid-length gas system helps promote smooth cycling, while the Super Modular Rail (SMR) with M-LOK provides a rigid, lightweight mounting platform for lights, grips, and other accessories. The upper also includes Geissele’s Reliability Enhanced Bolt Carrier Group (REBCG) and an Airborne Charging Handle for dependable operation and confident handling.
