The Kel-Tec RFB (Rifle, Forward-ejecting Bullpup) is a .308 Winchester bullpup semi-automatic that ejects spent cases forward out of a chute above the handguard. This forward ejection makes the RFB fully ambidextrous — no conversion or modification needed for left-handed shooters. It accepts standard FAL metric magazines. The 18-inch barrel in a 26-inch overall length package delivers full-power .308 ballistics in a very compact form. Type: Rifle Action: Semi-Automatic Caliber: 7.62x51mm NATO Capacity: 20 Year introduced: 2009, USA Weight: 96 oz Overall length: 26" Status: Active Intended use: tactical, sporting, precision
