Looking to save weight on your AR-15? If you've shaved ounces off by choosing the Brigand Arms carbon-fiber handguard, then the Brigand Arms M-LOK Aluminum Backing Plate is the accessory you need to attach lights, lasers, grips and other add-ons without bulking up your already-trim handguard. This backing plate enables users to attach all the accessories of their choice without adding heavy Picatinny-rail segments that cancel out all the weight-saving benefits of the carbon-fiber handguard. Each plate weighs just 0.26 ounce, and the screws and hex wrench needed for installation are included.
