The KelTec RDB 5.56 NATO Black is a bullpup rifle with a 17-inch barrel and a 20-round magazine (KelTec part no. RDBBLK). KelTec ejects spent casings downward and away from your line of sight, with fully ambidextrous controls so it fires from either shoulder. The center of gravity stays over the grip, which makes the rifle balanced during extended use. It accepts AR-15 style magazines and suits range, home defense and general-purpose shooting.
