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

The Kel-Tec RDB20GRN RDB 223 Rem rifle represents a modern evolution of the bullpup platform, engineered for operators and shooters who demand compact handling without sacrificing ballistic performance. This 20-inch rifle delivers full 5.56 NATO/.223 Remington velocity in a footprint significantly shorter than traditional rifle layouts, making it ideal for close-quarters tactical environments, vehicle operations, and home defense scenarios where maneuverability matters. The RDB series addresses a critical gap in the bullpup market by combining genuine ambidextrous operation with reliability, appealing to law enforcement, military personnel, and civilian tactical shooters alike.

The defining feature of the Kel-Tec RDB20GRN is its patented downward-ejection system—a mechanical innovation that eliminates the traditional bullpup ejection hazard of spent casings striking shooters in the face or neck. This design allows truly ambidextrous operation; both left- and right-handed shooters can manipulate the rifle with equal efficiency without modification or part swapping. The 20-inch barrel provides optimal velocity for .223 Remington loads while maintaining the compact overall length that distinguishes the bullpup design, delivering superior ballistic advantage in intermediate-range engagements compared to shorter AR-15 setups.

Law enforcement tactical teams, military designated marksmen, and home defenders benefit most from the RDB20GRN's balance of maneuverability and ballistic authority. The 20+1 capacity configuration provides operational flexibility in high-round-count scenarios, and the rifle's compact profile excels in vehicle extractions, building entries, and confined-space operations where traditional full-length rifles prove unwieldy. The completely ambidextrous controls—combined with its downward-ejection advantage—make the RDB20GRN an exceptional choice for training diverse shooter populations or mixed-handed tactical teams without requiring platform-specific instruction variations.
