Kel-Tec RDB-C 223 Remington / 5.56 NATO 20.5" 10-Round Bullpup Rifle

The Kel-Tec RDB-C is a semi-automatic bullpup rifle chambered in .223 Remington and 5.56x45mm NATO. Its bullpup layout places the action behind the trigger to keep the overall length compact while preserving a 20.5-inch barrel. The rifle uses a downward-eject design that routes brass and gas away from the shooter's line of sight, allowing it to be fired from either shoulder.

The RDB-C has a black polymer finish, a fixed stock, and a 10-round capacity. Its adjustable gas system can be tuned for different ammunition loads, which helps reliability and recoil behavior. The rifle is suited to shooters who want the RDB platform in a simplified, fixed-stock configuration.
