Kel-Tec RDB20GRN RDB 223 5.56 NATO 20" 21-Round Bullpup Rifle

The Kel-Tec RDB20GRN RDB 223 5.56 NATO 20" 21-Round Bullpup Rifle represents a modern take on compact rifle design, purpose-built for shooters who demand firepower without sacrificing maneuverability. This bullpup-configuration rifle serves law enforcement, military personnel, and civilian operators requiring a platform that delivers rifle-caliber performance in a carbine footprint. The forward magazine well and rear firing group geometry make the RDB an intuitive platform for trained shooters transitioning from conventional rifle ergonomics.

The 20-inch barrel delivers full-velocity 5.56 NATO and .223 Remington performance while the 21-round magazine capacity provides substantial firepower for tactical applications and training scenarios. The bullpup design places the action directly behind the trigger, minimizing overall length while maintaining sight radius and ballistic efficiency—critical factors in close-quarters or vehicle-mounted operations. Kel-Tec's engineering emphasizes a modern ergonomic profile with controls positioned for rapid manipulation, allowing ambidextrous operation and fast magazine changes under pressure.

Operators in law enforcement, military units, and precision-focused civilian markets benefit most from the RDB's compact profile and rifle-class ballistics. The platform accepts standard 5.56 NATO ammunition and integrates seamlessly into existing armory ecosystems. Installation of optics, suppressors (with appropriate threading verification), and tactical accessories follows conventional AR-pattern rail standards, making the RDB compatible with mainstream tactical gear and mounting solutions used across modern weapon systems.
