The definitive modular combat rail is now also available in an Aircraft
Grade Aluminum alloy. With seven mounting surfaces, the KMR-Alpha is a
modular handguard that uses the KeyMod system to attach accessories such
as lights, lasers, vertical grips, handstops and more.
Utilizing the same patented (US 8904691) free float barrel nut lock up, the KMR-Alpha uses the identical mounting hardware as the original KMR. This new addition to the KMR family only weighs 6 ounces plus 2.2 ounces for barrel nut and hardware (Note: KMR-A10).
Each KMR-Alpha includes a BCM® KeyMod QD Sling Mount and is available in 15", 13" and 10" as well as 9", 8" and 7" sizes.
|The KMR uses a patented lock up system where self-locking cross bolts apply force at the 12:00 position of the handguard equally distributing force around the surface area of the rail. This also insures continuous top center alignment of the rail and mitigates forwards/backwards movement of the handguard when the weapon system is fired.|
