The QRF Series of handguards from BCM builds upon the company's industry-leading barrel nut and lock-up design, initially introduced with the innovative KMR handguard. Tailored for shooters seeking modularity in the picatinny (MIL-STD-1913) platform, this handguard ensures a customizable and reliable setup for your firearm. Each of the four rails features T, L, R, and B recoil slot markings, making it easy to establish a consistent and repeatable configuration. At the core of the QRF Series' reliability is BCM's proprietary patented mounting system (US Patent 8904691). This advanced system incorporates a mechanical index to the 12:00 rail, strategically positioning mounting hardware to combat any movement caused by the heat generated during weapon use. Whether you're a novice enthusiast or an experienced operator, the QRF handguard offers unmatched stability and precision, ensuring your weapon performs at its best in any condition. Invest in BCM’s QRF Series for superior modularity, durability, and performance.
