Description

The Geissele Super Duty 11.5″ Barreled Upper Receiver is a hard-use, duty-focused upper built for reliability, durability, and consistent performance in demanding conditions. It features a cold hammer forged 11.5″ CMV barrel with a 1:7 twist and chrome-lined bore, paired with a carbine-length gas system and Geissele’s Super Compact gas block for dependable cycling. The included 10.5″ Super Modular Rail MK16 provides a rigid, lightweight mounting platform with a proven profile for duty and tactical use.
This is a barreled upper receiver configuration—no bolt carrier group, charging handle, or muzzle device included—making it an ideal foundation for agencies and individual builders who want to choose their preferred internals and muzzle setup. Finished in Desert Dirt Color (DDC), note that Geissele’s DDC is intentionally variable and not intended for exact color matching across parts.
