This Super Duty MOD 1 uses a 16-inch threaded barrel paired with a closed-end three-prong flash hider and a direct impingement operating system. Chambered in 5.56mm NATO with a 30+1 capacity, it delivers the standard AR-15 format with Geissele’s component selection and attention to detail.
The slick-side upper omits the forward assist while retaining a shell deflector and ejection-port cover. A Geissele-marked bolt carrier is visible through the ejection port. The free-float aluminum M-LOK handguard uses M-LOK QD adapter plates for sling attachment and a continuous 12-o'clock Picatinny rail with T-marks running across the upper and handguard for repeatable accessory placement.
Controls are fully modernized: an ambidextrous safety selector, an ambidextrous paddle-style magazine release, and an ambidextrous charging handle with enlarged levers support efficient manipulation from either side. The flat-faced trigger and an integral enlarged trigger guard in the lower enhance control and access.
Magpul furniture rounds out the build with a Magpul MOE PR collapsible stock and a Magpul MOE+ pistol grip. The stock is polymer and finished in black, with a 13.0-inch length of pull. QD sling swivels are already installed on the handguard for fast sling setup.
