KDG MREX M-LOK Rail Extension for FN SCAR 15P – Black

Upgrade your FN SCAR 15P with the Kinetic Development Group (KDG) MREX M-LOK Rail Extension in Black. Engineered specifically for the SCAR 15P pistol, the MREX delivers a seamless, rock-solid handguard extension that attaches directly to the factory rail without tools—giving you more real estate for accessories, better support hand placement, and a more ergonomic shooting experience.

Precision-machined from aircraft-grade aluminum, the MREX features full M-LOK compatibility along with a continuous top Picatinny rail that indexes flush with the SCAR’s receiver rail for a smooth, uninterrupted surface. Its lightweight, low-profile design adds minimal bulk while significantly expanding your mounting options for lights, lasers, grips, and other tactical accessories.

Whether you’re running the SCAR 15P as a home defense pistol, a competition build, or a suppressed SBR, the KDG MREX is a professional-grade upgrade trusted by serious shooters. At Deep Roots Rifle Co, we stock hard-to-find SCAR accessories like this one so you can get exactly what you need without the wait.
