The Punisher-logo lower is machined from 7075-T6 aluminum and finished in matte black Type III hard-coat anodizing. Matching construction on the DS-15 upper ensures tight fit and long-term durability, while the engraved DSI shield logos on the upper, charging-handle latch, and buffer-tube end plate confirm factory provenance.
A 16-inch stainless/CMV barrel with a recessed crown optimizes accuracy and corrosion resistance. Surrounding it is a 15-inch aluminum free-float handguard that is skeletonized for weight reduction, ventilated with M-Lok slots, and topped by a full-length Picatinny rail for optics or iron sights.
The nickel-boron coated bolt carrier group delivers smooth cycling and simplified cleaning. An upgraded single-stage flat-face trigger shortens perceived pull length and offers a crisp break for precise shot control.
Furniture includes a 6-position adjustable stock, a Magpul MOE pistol grip, and standard AR controls. Chambered in .300 AAC Blackout, the rifle feeds from standard STANAG magazines and is ready for subsonic or supersonic loads.
