The KAC URX 4 MLOK Forend 556 8.5" Blem is a premium modular rail system designed for AR-pattern rifles chambered in 5.56 NATO. This forend is built by Knights Armament Company, a manufacturer known for its reliability and quality, especially among military and law enforcement professionals.
The URX 4 features an 8.5-inch length and integrates MLOK (Modular Lock) slot architecture, allowing for customizable attachment of accessories such as lights and grips. Weighing 1.38 lbs, this forend minimizes front-end mass while ensuring structural rigidity for consistent zero retention and durable optic mounting. The black anodized finish provides corrosion resistance and reduces glare.
Ideal for competitive shooting, tactical training, and duty-ready configurations, the URX 4 allows users to position accessories without rail clutter. The included shim set and proprietary wrench facilitate tool-less adjustments for compatibility with various upper receiver designs. The blem designation indicates minor cosmetic imperfections on the rail itself, making it a cost-effective choice for serious users.
