Description
Product Overview
The Head Down HDX-M4-556 Triton is a semi-automatic modern sporting rifle built around the AR-15 pattern and chambered for .223 Remington and 5.56 NATO. Its 16-inch phosphate and chrome-lined 4150 steel barrel is designed for durability and corrosion resistance, while the precision-milled billet upper and lower receivers provide a robust foundation. A Carpenter 158 bolt carrier group receives high-pressure testing and magnetic particle inspection, with the gas key properly staked for reliable operation. The rifle includes a standard mil-spec six-pound trigger, integral trigger guard, flared magazine well, collapsible synthetic stock, and a black Type III hardcoat anodized finish. The flat-top receiver is optic ready, and the threaded muzzle supports compatible accessories.
