Geissele Super Duty MOD1 Features
At the heart of this upper is a 10.3 inch chrome-lined barrel forged in-house by Geissele for extreme longevity and accuracy. The 1 in 7 inch twist rate provides excellent stabilization for heavier 5.56 projectiles. Out front, a HUXWRX QD-compatible flash hider allows for fast suppressor attachment while minimizing flash signature.
The upper includes a free-floating M-LOK handguard, providing a lightweight yet rugged mounting surface for mission-critical accessories. Inside, the Reliability Enhanced Bolt Carrier Group (REBCG) features a Nanoweapon coating that resists wear, corrosion, and carbon buildup. The included Geissele Airborne Charging Handle ensures smooth, ambidextrous operation under stress.
This upper ships fully assembled and ready to mount on your lower receiver, with an overall length of 19.5 inches and a weight of 3 pounds 7 ounces, making it an ideal balance of compactness and capability.
