The Kel-Tec RFB is a gas-operated semi-automatic bullpup rifle chambered in .308 Winchester and 7.62x51mm NATO. Its 18-inch barrel sits inside a 26.1-inch overall length, and the rifle weighs 8.7 pounds. Forward ejection sends spent cases over the barrel, so the rifle works for right- or left-handed shooters without changing its ejection pattern. The magazine holds 20 rounds. This Blue/Black model has a green synthetic stock, standard sights, an optic rail and a threaded barrel.

A compact rifle with full-power chambering suits a shooter who wants .308 performance in a short package for range work, field use or defensive applications, which the supplier lists. The ambidextrous safety and forward ejection make the rifle usable from either shoulder. Check your state's rules on age and features before you buy, because they apply at pickup.
