Product DescriptionThe Bravo Company BCM MCMR-10 is a lightweight, high-strength, M-LOK compatible free-float modular rail handguard designed for AR-15/5.56 platforms. Built from precision-machined 6061-T6 aerospace aluminum alloy, it uses BCM's proven barrel nut and lock-up design (originating from the KMR series) to deliver a rigid, repeatable mounting interface. Its proprietary patented mounting system incorporates a mechanical index at the 12 o'clock rail and positions mounting hardware to help mitigate movement caused by weapon heat. With an actual flare-to-flare length of 10.5 inches, the MCMR-10 is engineered to work with pistol-, carbine-, or mid-length gas systems when paired with a low-profile gas block.Product Highlights M-LOK compatible free-float handguard helps reduce barrel deflection for improved accuracy potential. Precision-machined 6061-T6 aluminum construction balances durability, rigidity, and low weight. Proprietary BCM barrel nut/lock-up system with mechanical indexing at the 12 o'clock rail for consistent alignment. Optimized profile for added cross-sectional strength while maintaining a slim handling feel. Includes factory hardware and tools for installation (and includes an M-LOK sling mount per listing details).Specs Brand: Bravo Company Model: MCMR-10 Type: Modular rail / handguard Platform/Fit: AR-15 / 5.56 (AR rifles) Mounting Interface: M-LOK compatible Length: 10.5 in (measured to flare) Inside Diameter: 1.3 in Width: 1.5 in Material: 6061-T6 aluminum alloy Barrel Nut Fitment Note: Fits over mil-spec diameter barrels (max 1 in) Barrel Nut Material: Steel Finish: Hard coat anodized (Mil-A-8625F, Type III, Class 2) Color: Black Weight (handguard only): 6.6 oz Weight (mounting hardware): 2.3 oz Patent: US 8904691 Included: Factory hardware and tools; M-LOK sling mount (per listing details) UPC: 812526021632 Manufacturer Part Number: BCM-MCMR-10-556-BLKDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
