Product DescriptionThe Bravo Company BCM QRF-10 (Quad Rail Free Float Handguard) is a one-piece free-float quad rail designed to deliver a rigid, repeatable MIL-STD-1913 Picatinny mounting platform for AR-pattern rifles. Built around BCM's proprietary barrel nut and lock-up system (US Patent 8904691), the QRF-10 uses a mechanical index to the 12 o'clock rail and a steel barrel nut to help resist movement from heat. Integrated T/L/R/B recoil-slot markings on all four rails support consistent accessory placement, while the free-float design helps reduce barrel deflection for improved accuracy. Four limited-rotation QD sling swivel sockets are included for versatile sling mounting.Product Highlights Free-float quad rail handguard with MIL-STD-1913 Picatinny rails for broad accessory compatibility Proprietary BCM barrel nut and lock-up system with mechanical 12 o'clock indexing (US Patent 8904691) Steel barrel nut designed to resist movement under heat Integrated T, L, R, and B recoil-slot markings for repeatable accessory setup Four limited-rotation QD sling swivel sockets for flexible sling attachmentSpecs Brand: Bravo Company Model/Series: BCM QRF-10 / BCMGUNFIGHTER Product Type: Free-float quad rail handguard Platform Compatibility: AR rifles / AR-15 Caliber Compatibility: 5.56 Rail Type: Picatinny (MIL-STD-1913), 4-sided quad rail Color/Finish: Black, hard coat anodized (Mil-A-8625F Type III, Class 2) Material: 6061-T6 aluminum Barrel Nut Material: Steel Inside Diameter: 1.3 in Overall Width: 2.12 in Actual Length: 10.36 in Maximum Barrel Diameter: 1.0 in Weight: 9.8 oz Mounting Hardware Weight: 2.3 oz QD Sockets: 4 (limited rotation) Manufacturer Part Number: BCM-QRF-10-556-BLK UPC: 812526021496Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
