Geissele Super Duty Mod1 – Key Features

Built for shooters who demand consistency and durability, the Super Duty Mod1 is equipped with a 14.5" cold hammer forged barrel that reaches a legal 16" overall length once the muzzle device is pinned in place. Its 1:7 twist rate is ideal for stabilizing modern 5.56 and .223 projectiles, while the mid-length gas system provides smooth cycling and reduced recoil impulse.

The rifle comes fitted with a pinned and welded HUXWRX QD 556 flash hider, offering both effective muzzle control and compatibility with QD suppressors. Ergonomics remain a priority, pairing a B5 Enhanced SOPMOD stock and QD endplate with Geissele’s A17 grip for a secure, comfortable interface. A 13.5" SMR MK16 handguard sets the foundation for accessory setup and rigidity, utilizing the Center Tab Rail design for precise alignment. The SSA-E X trigger with Lightning Bow delivers a crisp, predictable pull, and the Airborne Charging Handle enhances ambidextrous handling.
