The KelTec RDB 17-inch tan bullpup rifle in 5.56mm (KelTec part no. RDBTAN) puts the action behind the grip so a long barrel fits in a compact, well-balanced package. Spent casings eject downward and out of the shooter’s line of sight, which makes the rifle shoot the same from either shoulder, and the controls are fully ambidextrous. At 17 inches, the barrel is a little shorter than the 20-inch RDB while keeping the same layout.
