BCM Gunfighter Quad Rail Black 12-inch Free Float

Overview

BCM QRF Features The BCM QRF free-float quad rail is precision machined from aerospace 6061-T6 aluminum alloy using a proprietary engineered profile that delivers additional cross-sectional strength without unnecessary weight resulting in a handguard that is both rigid and lightweight at 15.1 ounces for the handguard alone. The patented mounting system covered under US Patent 8904691 incorporates a mechanical index to the 12 o clock rail and positions mounting hardware to mitigate movement caused by heat generated during sustained fire. A steel barrel nut shared across the KMR MCMR and QRF series resists movement under heat and fits over all Mil-Spec diameter barrels up to a maximum of 1 inch. For precision rifle builders and duty professionals who demand repeatable zero and handguard stability under hard use the QRF mounting system delivers a lock-up that holds position through extended round counts. The hard coat anodized finish meets Mil-A-8625F Type III Class 2 specification providing durable corrosion and abrasion resistance suited to field and duty environments. An inside diameter of 1.30 inches and outside width of 2.12 inches give the QRF a comfortable hand-filling profile that works well with gloves and supports a consistent shooting grip across a range of hand sizes. Recoil slot markings labeled T L R and B on all four rails aid in repeatable accessory setup and four included QD sling swivel sockets with mounting hardware allow immediate sling attachment without additional modification. For AR-platform shooters building a modular accessory-ready rifle with a proven free-float rail system the BCM QRF is available now at GrabAGun.
