Geissele SD 5.56X45 NATO Semi-Auto Rifle – 16″ Barrel

The Super Duty MOD1-A builds on the proven performance of the MOD1 platform while introducing fully ambidextrous controls for enhanced versatility and control in dynamic shooting environments. Designed with the same intuitive layout found in Geissele’s professional-grade rifles, this system enables efficient manipulation from either side. A left-side magazine release and right-side bolt catch and release controls streamline reloads and malfunction clearances, allowing faster, more consistent operation without breaking grip.

Engineered for durability and precision, the platform features a cold hammer forged barrel and a Forged Stressproof Bolt made from enhanced Carpenter 158+ steel, both high-pressure tested and magnetic particle inspected for long-term reliability. A finely tuned gas system, paired with a compact gas block and braided buffer spring, reduces recoil while maintaining consistent cycling. The two-stage trigger delivers a crisp, predictable break, while the included HUXWRX Flash Hider QD supports suppressor compatibility. Complemented by a rigid free-float rail, adjustable stock, ergonomic grip, and integrated QD sling mounting points, the MOD1-A offers a balanced combination of performance, control, and adaptability.
