Kinetic Development Group SCAR MREX MKII M-LOK 4.25" Handguard

New for 2019, is the KDG SCAR MREX MKII Rail Systems for the FNH SCAR rifle Platforms. There are a few obvious differences / updates from the original MREX. M-Lok slots are present in more locations than the previous model, spanning the entire length of the MREX MKII. M-Lok has been added to the 2 o'clock and 10 o'clock position as a new mounting location and shield from the gas block. The MKII has the desired step down forward of the front folding sight like the MREX, but no picatinny. The traditional picatinny in this 12 o'clock position has been replaced with M-Lok slots allowing for more mounting options. These designations signify the length the MREX MKII extends (in inches) beyond the SCAR upper receiver. The 6.5" length is the ideal full size rail extension, same as its predecessor (MREX M-Lok 6.5). They have updated the MREX M-Lok 4.9 (Mid-length) to an overall length of 4.25" to accommodate the needs of issued rifle users. This length is ideal for use on a SCAR MK17 with a 13"
