The Kel-Tec RDB in .223 Remington is a bullpup rifle with a 20-inch barrel and a 30.6-inch overall length. It weighs 7.1 pounds and comes in a blue and black finish. The rifle takes a 20-round magazine, and one is included. A 1:7 twist barrel suits a range of projectile weights, and folding front and rear sights sit alongside a top rail for an optic. The ambidextrous controls and downward shell ejection make it usable from either shoulder.

This version suits a buyer who wants .223 Remington chambering in a short package with a full-length barrel. Owners can run AR-15 pattern magazines, and the top rail lets them add a red dot or scope without giving up the folding sights. It is a practical choice for range shooting and training.
