RFB stands for Rifle Forward-ejecting Bullpup. Why forward-ejecting? Because it allows the RFB to be the first truly ambidextrous 7.62 NATO Bullpup ever developed. The patented dual-extractor system maintains control of the case from the moment it leaves the magazine and upon firing pulls the fired case from the chamber and lifts them to push them into an ejection chute above the barrel where they exit. The Bullpup configuration and tilting-block mechanism allow the 18.5" model to be only 26.1" long or as much as 14" shorter in overall length than its competitors with equal barrel lengths. Furthermore the stock and mechanism cross-section is similar to a conventional rifle in stark contrast to existing Bullpup rifles. The RFB is also the safest Bullpup ever developed because the breech is separated from the shooters face by two layers of 1.6 mm steel. In the highly unlikely event of a case rupture gas expansion is directed downwards through the magazine well to protect the shooters head and face.
