The BCM MCMR 15" handguard transforms AR-platform rifles with a lightweight, rigid mounting system that maintains zero under rapid fire and temperature changes. This free-floating design eliminates barrel contact for enhanced accuracy potential while providing extensive M-LOK attachment points for accessories.
What Makes This Different
Unlike standard drop-in handguards, the MCMR (Modular Compatible Modular Rail) system uses a proprietary barrel nut that creates a rock-solid connection to the upper receiver. The 15-inch length covers most standard barrel profiles while weighing just 11.8 ounces. Internal anti-rotation tabs prevent shifting under heavy use, and the slim 1.5-inch outer diameter maintains comfortable handling.Key Features
