The Mk3 CBR (Carbine Battle Rifle) is chambered in .308 WIN/7.62x51mm NATO and is precision-built to deliver the relentless functionality that CMMG rifles are known for. The Mk3 CBR is an ideal rifle for long-range shooting or close-quarters action and because it’s built with CMMG’s premium manufacturing requirements, it gives shooters the chance to own a high-end AR rifle at a practical price. The Mk3 CBR features the free-float RKM15 KeyMod hand guard that measures 15 inches in length to accommodate a wide range of hand positions and allows users to attach an assortment of different accessories. The KeyMod slots are located at the 3, 6 and 9 o’clock positions with a 1913 Picatinny rail on top to give the hand guard an array of mounting options. The KeyMod system is the new industry standard for mounting accessories. It is a simple, comfortable and lightweight solution that offers users a low-profile mounting alternative to the M1913 Picatinny rail. The KeyMod system presents a new level of customization, as it allows the direct attachment of compatible accessories without the use of intermediate M1913 Picatinny rails. For accessories that are not yet KeyMod compatible, users can purchase a separate CMMG 5-slot Picatinny adapter rail that can be easily attached to any of the KeyMod slots for optimal placement of the accessories. The Mk3 CBR rifle is constructed with a hard-anodized, billet 6061-T6 aluminum receiver. A 416 stainless barrel was selected and features a nitride finish that provides the barrel with long-lasting accuracy and corrosion resistance. CMMG’s medium taper (MT) barrel is the perfect balance between weight and rigidity. The rifle also includes a CMMG SV muzzle brake, designed to reduce recoil and increase muzzle control for quick and manageable follow-up shots. By partnering with other industry leaders, the Mk3 CBR has some of the best components available to complete the rifle. Some of these parts include a Geissele Automatics SSA® 2-stage trigger, a Magpul ACS-L™ collapsible butt stock and Magpul MOE® pistol grip. The rifle also comes with a Magpul 20 LR PMAG® with a 20-round capacity. The combination of all of these features creates one of the most capable and affordable .308 WIN rifles available.
