BCM MCMR-1913-A3 3" Picatinny Rail Section - M-LOK Aluminum

The BCM MCMR-1913-A3 is a 3-inch Picatinny rail section machined from hard anodized aircraft aluminum alloy and built to Mil-Standard 1913 Picatinny Arsenal specifications. Designed for M-LOK compatible handguards, this 5-slot section gives you a snag-resistant mounting platform for lights, lasers, and other accessories on your rifle build.

Featuring a self-contained assembly with a 0 MOA orientation and a black anodized finish, the MCMR-1913-A3 mounts directly to any M-LOK slot for a secure, low-profile attachment. The 3-inch length is ideal for positioning backup iron sights, weapon lights, or other accessories without adding unnecessary bulk or weight to the handguard.

Manufactured by Bravo Company Manufacturing (BCM), the MCMR-1913-A3 is a precision-machined aluminum rail section that meets the same quality standards BCM applies to its complete rifles, handguards, and components. Whether you are upgrading an existing build or replacing a worn rail section, this M-LOK Picatinny section offers the durability and tight tolerance fit you expect from BCM.
