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.

The new KDG Modular Optic Mount is based off the proven Sidelok family of quick detach optic mounts, and features the same user-friendly, toolless design. KDG set out to design a Sidelok mount for all common, tube-style optics that will offer more user-configurable options than what is currently available from competing QD mounts. The Modular Optic Mount currently comes in three configurations, with ring sizes for 1”, 30mm and 34mm tubes.

The lightweight aluminum mount uses KDG’s Sidelok (pat. pending) cam lock system to attach to all picatinny rails instantly. With zero tools needed to attach the mount, the user simply rocks their optic onto the chosen mounting space, and down onto the rail. Once pressed down, the Modular Optic Mount self-locks, and the optic can be zeroed in the usual fashion. Removal is equally fast, and can be accomplished with one hand even while wearing gloves. The front located release button has a smaller, recessed secondary lock, which must be deliberately pressed in and to the rear to facilitate removal. The Sidelok system makes it virtually impossible to accidentally engage the release, and its cam lock system ensures a secure grasp on various sized (and some out of spec) picatinny rails. This equates to a fast, easy means of removing and attaching optics while retaining an absolute return to zero. 

The mount is offered with a user removable cantilever bar, in which the rings securely mount. This bar runs parallel to the weapon’s bore, and is ideal for all semi and fully automatic carbines, rifles and DM style firearms. KDG plans to release a separate 20 MOA bar in the future, for those that might require the added elevation for particular optic or application. 

The matched front and rear rings are CNC machined, and wire EDM cut to be as precisely concentric as possible. The upper and lower ring remain matched for the duration of its production, and feature witness marks for assembly in the form of recessed dots. This allows the user to match the proper ring to its base, and ensure the mount is as truly aligned as possible. The rings themselves can be adjusted forward or back to the user’s preference, to avoid interference with large front objective bells, turret adjustment knobs, and rear magnification adjustment collars. The rings themselves bolt into a track system to facilitate this adjustment. The same track system allows the user to purchase and install separate rings in the future, should they decide to change to an optic with a larger or smaller diameter tube. This feature will save the shooter or organization money, as the majority of cost is in the base of the unit. 

The Modular Optic Mount is now available to order on Kinetic Development Group’s website, and from authorized dealers. The 1”, 30mm, and 34mm mounts come with all hardware and instructions needed for immediate assembly, and will fit nearly all popular magnified optics currently on the market. With an MSRP of $224.99, the Modular Optic Mount just might be the last mount you ever need to buy. For more information, please check out kineticdg.com.
