Geissele Automatics Super Duty Mod1, Semi-automatic Rifle, 223 Remington/5.56 NATO, Sprdty 16″ Black

Product Description

Geissele Automatics Super Duty MOD1 is a semi-automatic AR rifle chambered in .223 Remington/5.56 NATO with a 16″ cold hammer forged barrel. The barrel has a 1:7″ twist and carries a HUXWRX QD 556 flash hider. The gas system is Geissele-length, and the finish is black anodized.

Geissele describes the MOD1 as the current evolution of its Super Duty platform, shaped by ongoing design work aimed at better ergonomics and modularity. The parts list shows where that work went. The trigger is the SSA-E X with Lightning Bow. The charging handle is the Airborne model. The buffer tube is 7075-T6 mil-spec with a QD endplate, and it runs a Super 42 braided buffer spring.

Furniture and handguard

The rifle comes with a B5 Enhanced SOPMOD stock with a QD endplate and a Geissele A17 grip. Up front is a 15″ SMR MK16 handguard with the Geissele center tab rail. These are Geissele-selected parts, so the rifle is set up as a complete build rather than a base to upgrade.

The Super Duty MOD1 suits shooters who want a 16″ AR with a quality trigger and good controls for range days, training classes, or a general-purpose carbine. Pair it with a red dot or magnified optic, a sling that uses the QD endplate, a weapon light, and a set of quality magazines.
