The BCM QRF Handguard is a 10-inch, free-float quad rail built with Picatinny rail on all four sides for AR-platform rifles (brand part no. BCM-QRF-10-556-BLK). Bravo Company Mfg / BCM precision machines it from aerospace-grade 6061-T6 aluminum alloy with a proprietary engineered profile that adds cross-sectional strength while keeping weight down, and secures it with a steel barrel nut that resists movement under heat. At a 1.30-inch inside diameter and 2.12-inch outside diameter, it stays trim while offering full rail coverage. It ships with four QD sling swivel sockets and all mounting hardware, ready to install on a duty or range-focused AR build.
