This Super Duty is an AR-15 platform rifle with a direct impingement gas system, a 16 inch threaded barrel, and a factory-installed three-prong flash hider. Its flat-top upper includes a forward assist and ejection-port dust cover, and the rifle uses the standard STANAG/AR-15 magazine interface for broad magazine compatibility.
The free-float aluminum M-LOK handguard measures approximately 15 inches and provides a continuous, T-marked 12 o'clock Picatinny rail for mounting. It is secured with anti-rotation fasteners and a center-tab interface for a solid fit.
Controls and ergonomics include an ambidextrous extended-latch charging handle, a manual safety, and a textured polymer pistol grip with a beavertail. The B5 Systems adjustable carbine stock offers a QD sling socket and rides on a 6-position receiver extension. Length of pull is approximately 13.5 inches.
A Geissele-marked bolt carrier group and a black anodized receiver finish round out the build. Capacity is 30+1 rounds. No iron sights or optics are installed from the factory.
