The KelTec RFB Quad Rail delivers a precision-machined, hard coat anodized 6061-T6 aluminum handguard extension designed for the RFB platform, measuring about three inches in length and accepting any accessories that mount with a standard MIL-STD 1913 Picatinny Rail attachment for versatile customization. Its two scalloped top cut-outs provide the shooter with the freedom to adjust the gas system when needed while ensuring ejected casings clear the ejection port for smooth operation, a feature that blends performance with practical field practicality. Care should be taken when choosing accessories for the left-hand side to avoid obstructing the ejection port, preserving reliable cycling during rapid follow-up shots. This quad rail assembly comes complete with the RFB-420 Quad Rail, a locking nut and wrench, and a set screw with Hex Key, offering everything you need for secure installation and future maintenance. Built to endure demanding environments, the KelTec RFB Quad Rail adds rigid mounting opportunities for optics, grips, and ancillary gear without compromising the rifles balance or integrity. Ideal for rifle enthusiasts seeking a reliable, modular handguard solution that enhances control, accessories compatibility, and field adaptability on the RFB platform.
