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.

Compared to the 4.9” version, both the 4.25” and 2.2” MK2 versions feature additional M-Lok slots at the 2 o’clock and 10 o’clock positions, providing new mounting options and shielding the gas block. The 2.2” version, ideal for 10” SBR configurations or SCAR users wanting M-Lok compatibility without extending beyond the gas block, offers similar improvements with a compact design tailored for shorter setups.
