Product DescriptionThe Bravo Company BCM MCMR-15 is a lightweight, M-LOK compatible modular rail handguard engineered for hard-use AR-15 5.56 platforms. Built from precision-machined aerospace-grade 6061-T6 aluminum, it uses BCM's proven barrel nut and lock-up design first introduced on the KMR series. Its patented mounting system (US Patent 8904691) mechanically indexes to the 12 o'clock rail and helps mitigate accessory shift caused by heat. With an actual length of 15 inches (measured to the flare), the MCMR-15 is designed to work with pistol, carbine, mid-length, or rifle-length gas systems when paired with a low-profile gas block, and it includes factory hardware and tools for installation.Product Highlights M-LOK compatible modular handguard for flexible accessory mounting on AR-15 5.56 builds Precision-machined 6061-T6 aluminum construction for high strength at a lightweight profile BCM barrel nut and lock-up design with patented mechanical indexing to the 12:00 rail (US Patent 8904691) 15-inch actual length (to flare) ideal for extended support-hand placement and accessory spacing Includes factory hardware and installation tools; fits over mil-spec barrels up to 1" max diameterSpecs Brand: Bravo Company Model/Series: BCM MCMR-15 Type: Modular rail handguard Platform/Caliber Compatibility: AR-15 / 5.56 Mounting Interface: M-LOK Color/Finish: Black Length: 15 in (actual length measured to flare) Inside Diameter: 1.3 in Width: 1.5 in Barrel Compatibility: Barrel nut fits over mil-spec diameter barrels (max 1" diameter) Material: Aerospace 6061-T6 aluminum alloy Gas System Compatibility: Pistol, carbine, mid-length, or rifle-length (with low-profile gas block) Included: Factory hardware and tools UPC: 812526021618 Manufacturer Part Number: BCM-MCMR-15-556-BLKDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
