Kinetic Development Group (KDG) is proud to announce the debut of their first SCARcentric product – the MREX.

The SCAR is one of the most tested, reliable high-end weapons systems of our time. USSOCOM has put more rounds through the SCAR in testing than any other small arms platform in US history. Our forces have carried it into battle against our enemies on multiple continents. It can be accurately said that the SCAR is reliable and durable as an AK and as light and accurate (and nearly as ergonomic) as an AR15/M4.


It is a well engineered carbine…but what the heck happened when the FN Engineers designed the front end of the SCAR? Many shooters compare it to a 6 inch piece of 2×4 with cheese graters on all 4 sides! Where are you supposed to put your support hand if you have even one accessory mounted to those plastic rails?

Darren Mellors, David Loeser and AJ Lafferty, formerly of LWRCI, founded Kinetic Development Group to find solutions to problems with various high quality small arms platforms. The team recognized this as one of the shortcomings of the FN SCAR L/H.

KDG cringed at the thought of our troops dealing with the crowded front end of a weapon that seemed to have forgetten the shooter must be able to grasp it effectively. The standard SCAR forend forces Warfighters to compromise on the way they shoot as well as their choice of accessories. There should be no need for such a compromise, so KDG set out to make a change.

KDG - Outdoor 1You can buy any number of ‘cheese grater’ Picatinny forearm extensions to bolt on in the hopes of increasing effectiveness. However, by adding the MREX forearm, you have the certainty of doing so. The shooter will have room not just for desired accessories, but also more area to comfortably grip the rifle. Changing the barrel on a SCAR while using other ‘furniture’ systems can be a difficult ordeal. Where other receiver extensions fail the MREX succeeds by allowing quick change of different barrel assemblies. KDG offers three lengths to accommodate standard and short barrels, and offer negative space mounting options in MLOK and the KDG standardized modular rail system.


The MREX is also compatible with FN’s MK-13 EGLM grenade launcher with the MREX Grenade Launcher accessory kit.

With the MREX, a shooter need not adapt shooting technique to properly use a properly equipped SCAR. The weapon itself is changed to suit individual needs and is done with engineering grace and precision. The MREX solution adds minimal weight to the firearm; what it does add is minimal and well balanced. It increases the accessory capability, improving proper placement and increasing weapon ergonomics, for instance by offering a rail step-down in front of the BUIS to mount lights and lasers. Mounting your PEQ here not only tucks it away with a very low profile, but also reduces the height over bore axis reducing the offset of your IR laser illuminator.
