Geissele Super Duty Mod1

The Geissele Automatics Super Duty Mod 1 is a purpose-built AR platform engineered for durability, repeatable accuracy, and professional use. Chambered in .223 Remington / 5.56 NATO, this semi-automatic rifle centers on a 14.5" cold-hammer-forged barrel (pinned to achieve a 16.0" overall legal length) with a 1:7 twist that stabilizes a wide range of bullet weights. The muzzle is finished with a pinned-and-welded HUXWRX QD 5.56 flash hider for legal compliance while retaining a compact profile. A mid-length gas system smooths the recoil impulse for reliable, controllable follow-up shots, while the 13.5" SMR MK16 free-float rail with Geissele center tab provides an ultra-rigid mounting platform for optics and accessories. Built on high-quality 7075 receivers with a hard-anodized finish in tactical black, the Super Duty Mod 1 is fitted with user-focused ergonomics: B5 Enhanced SOPMOD stock with QD endplate and a Geissele A17 pistol grip for fast, repeatable handling and comfortable shooting. Designed for professional, duty, and precision-focused shooters who want a rock-solid platform out of the box, this Geissele Super Duty Mod 1 ships without a magazine so you can fit your preferred magazine type and capacity.
