The KDG FN SCAR 15P Rail - MREX15 (MRX5-MK2-015) is a compact, purpose-built handguard upgrade designed specifically for the FN SCAR 15P platform. As a shortened variant of KDG's proven MREX MKII system, it delivers enhanced ergonomics and modularity without adding unnecessary bulk to the firearm. Constructed from 6061-T6 aircraft-grade aluminum with a Type III hardcoat anodized finish, the MREX15 offers a strong yet lightweight solution, weighing approximately 2.6 ounces. Its M-LOK interface provides multiple mounting points for lights, lasers, grips, and other accessories, improving customization while maintaining a streamlined, low-profile design. Engineered for seamless integration, the rail installs as a drop-in upgrade and is optimized to enhance control, balance, and handling without extending past the upper receiver. The result is a more comfortable grip surface and improved maneuverability-making it an ideal upgrade for shooters looking to modernize and maximize the performance of their SCAR 15P platform.
