The Kinetic MREX™ Modular Receiver Extension is designed to be simple, durable, and lightweight. The slim profile of the MREX greatly improves the aesthetic of the SCAR by giving it a long sleek profile. Its extended rail length in front of the front sight/gas block increases the rifle’s modularity by increasing the real estate for accessory attachments as well as improves ergonomics by better accommodating the modern forward support hand rifle hold and improving the overall rifle’s balance. The MREX’s one piece construction ensures maximum durability without any significant weight penalty.
Compare with the 4.9” version, M-Lok slots are present in more locations in this 2.2” version, it 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 MK2 2.2” version is ideal for use with 10” SBR configurations, or any SCAR user looking to add M-Lok to their rifle without having a rail that extends beyond the gas block.
