The Kel-Tec RFB (Rifle, Forward-ejection, Bullpup) is a gas-operated bullpup type semi-automatic rifle, manufactured by Kel-Tec Industries of Florida. At the 2008 SHOT Show held from February 2 to 5 in Las Vegas, Nevada it was declared by Kel-Tec representatives that the RFB rifle would be made available to the public by the 4th quarter of 2008. Later, the Kel-Tec website stated that the 18 in (460 mm) barrel carbine variant would not be shipping until February 2009 due to a change in the production process intended as preventative measures against potential gun control legislation. The rifle first shipped to distributors in the first week of March 2009 and was first seen at the 2007 SHOT Show.

The RFB is a semi-automatic firearm chambered for 7.62×51mm NATO/.308 Winchester ammunition. The RFB uses metric FAL magazines, which insert straight into the magazine well and do not need to rock into place. It has a short-stroke gas piston operating system. The rifle uses a patented forward-ejection system via a tube placed over the barrel that ejects the spent case forwards, over the handguard of the rifle. Extraction is accomplished by two extractors, each with two axis of rotation. The extractors may move side-to-side to engage the rim of the case, and pivot upwards to extract the spent case after firing. Empty cases remain in the ejection chute until either the weapon is tilted downwards, the charging handle is operated, or they are pushed out by following cases. Cases drop gently from this chute to the left of the barrel. To avoid sloppy trigger pull typical of firearms modified into bullpups, the RFB uses a floating linkage bar between the sear and the hammer, allowing the sear to remain above the trigger. The weapon is fully ambidextrous, much in the style of the Belgian F2000 rifle. The RFB is delivered without iron sights. A mil-spec Picatinny rail is provided for mounting a wide range of optics and tactical accessories.
