The heart of this build is a limited-run Delaware Machinery forged 7075-T6 lower, hard-coat anodized in matte black. Its precise machining provides a solid foundation and full compatibility with standard AR components and STANAG magazines.
The 16-inch barrel features a 1:9 right-hand twist and a threaded muzzle capped by a three-chamber compensator. The multi-port design helps keep the muzzle flat during rapid strings, complementing the carbine-length gas system for reliable cycling.
A free-float aluminum quad-rail handguard offers numbered rail slots on four sides, giving clear reference points for lights, lasers, or the included detachable vertical fore-grip. The rail system also isolates the barrel from handguard pressure, aiding consistency.
Furniture includes a polymer bump-stock with an integrated thumb rest and 12.75-inch length of pull, plus an A2 front sight post and detachable A2 carry-handle rear aperture. Together they provide familiar iron sights while leaving room to mount optics on the upper’s rail segment if desired.
Bump stocks are not legal in all 50 states. Please verify compliance with your local and state laws before purchase.
