New 13.5” MREX AR forearm from Kinetic Development Group


KDG is proud to introduce its new 13.5” MREX AR forearm for AR-15 based weapons. The lightweight, ergonomic forearm is based off of their existing MREX AR design, and is a welcomed addition to their product line. The new 13.5” MREX AR forearm is affectionately nicknamed the “Roy Rail”, for all the help that Roy Lin of Weapon Outfitters provided KDG during its development. KDG interacted heavily with their vendor network as well as their core customer base, to determine which hand guard length would be most well received. With many shooters using a 16” or 14.5” barrel length, KDG determined that a 13.5” length forearm to be ideal for both.


The forearm weights in at 12.4 oz, complete with barrel nut and hardware, and is constructed out of the same high strength 6061 aluminum as their SCAR MREX rail. The free float design provides Seven M-Lok slots along the 3, 6, and 9 o’clock positions, with Picatinny rail running the full length of the forearm along the top. There are two additional rows of M-Lok at the 1 and 11 o’clock positions, to facilitate mounting weapon lights as low profile, and snag free as possible. The MREX contour was originally created to feel more like a traditional hand guard to the shooter, similar to the shape of a FAL or G3 forearm. With a flatter bottom then the majority of round tube forearms on the market, the MREX provides a superior profile for shooting off a rest, such as a bag or barricade. It’s ergonomics support a wide range of shooting styles and accessories, regardless if it is left “slick”, or used with vertical grips or handstops. Additionally there are two rotation-limited QD sockets located at the rear of the mil-spec anodized forearm. The 13.5” MREX ships as a complete kit, with shims, barrel nut tool and hardware.
