The Kel-Tec RFB Quad Rail and Riser Set (model RFB-425, UPC 640832001402) is a comprehensive accessory upgrade designed to enhance the tactical capability of your Kel-Tec RFB rifle. This excellent upgrade package significantly increases the rifle’s versatility by enabling it to be equipped with an array of modern tactical accessories. The riser is made out of hard coat anodized 6061-T6 aluminum, while the quad rail is made from hard coat anodized 6061-T6 aluminum and is approximately three inches long and will accept any accessories which mount with a standard MIL-STD 1913 Picatinny Rail attachment.
Two scalloped cut-outs on the top of the Picatinny allow the shooter freedom to adjust the gas system if needed and allow the ejected casings to leave the ejection port. The RFB Front Sight Riser mounts directly to the quad rail to produce an adequately tall front sight interface that is on the same plane as the RFB Receiver’s top rail, enabling the shooter to mount a fixed or flip-up front sight to the riser that will correctly align with a rear mounted iron sight.
The kit comes with one RFB-420-Quad Rail, one locking nut and wrench, and one set screw with hex key. Finished in black, this complete system provides a solid, repeatable platform for optics, lights, and other modern rifle accessories while maintaining the RFB’s operational reliability.
