KDG MREX MKII 4.25in Handguard for FN SCAR FDE

The Kinetic Development Group MREX Mark II is a modular handguard designed for FN SCAR rifles. It converts the SCAR into a more modular platform with extensive M-LOK mounting options and improved ergonomics. The MKII adds M-LOK slots along the full length of the handguard, including the 2 and 10 o’clock positions, and replaces the previous full-length Picatinny top rail with additional M-LOK options. This model extends 4.25 inches beyond the SCAR upper receiver and is described as suitable for use with a 13″ barrel and suppressor. It fits SCAR 16S and 17S models.
