Product Description The Kinetic Development Group (KDG) MREX Mark II is the next evolution of the acclaimed Modular Receiver Extension for the FN SCAR 16s and 17s. This 4.25" free-float M-LOK handguard has been engineered to extend beyond the SCAR upper receiver, providing shooters with a versatile, lightweight mounting platform for lights, lasers, and other accessories. Built from aircraft-grade 6061-T6 aluminum and finished with a Type III hard coat anodize in matte black, the MREX MKII offers exceptional durability without adding meaningful weight to your rifle. Compared to its predecessor, the MKII adds M-LOK slots at the 2 and 10 o&';clock positions and features simplified hardware for an easier installation process. This 4.25" length is specifically well-suited for use on a SCAR MK17 with a 13" barrel and an issued FNH suppressor, making it a proven choice for both civilian shooters and special operations personnel.
