Kel-Tec RDB20TAN RDB 223 5.56 NATO 20" 21-Round Bullpup Rifle

The Kel-Tec RDB20TAN RDB 223 5.56 NATO 20" 21-Round Bullpup Rifle delivers modern ergonomic rifle design in a compact platform optimized for tactical, defensive, and training applications. Built for shooters who prioritize maneuverability without sacrificing firepower, this bullpup configuration reduces overall length while maintaining a full-length barrel, making it ideal for close-quarters environments, vehicle operations, and home defense scenarios where space is limited. The 21-round magazine capacity provides substantial ammunition reserves, allowing operators extended engagement capability without frequent reloads.

The RDB20TAN features a 20-inch barrel chambered in 5.56 NATO, the NATO-standard intermediate cartridge trusted by military and law enforcement worldwide, ensuring compatibility with military-spec ammunition and reliable performance across diverse environmental conditions. The bullpup layout positions the magazine and action behind the trigger group, dramatically shortening the overall package to just 37 inches while the weight of 9.86 pounds keeps the rifle manageable for extended carry and shooting. This rear-heavy balance characteristic of bullpup rifles reduces muzzle rise during rapid fire, enhancing target reacquisition speed and control—a critical advantage in dynamic tactical scenarios where follow-up shot accuracy determines engagement outcomes.

Law enforcement tactical teams, military personnel, and civilian shooters operating in confined spaces find the RDB20TAN particularly valuable for its compact footprint combined with full-power rifle ballistics. The 5.56 NATO chamber makes it compatible with both commercial and military-grade ammunition, and the ambidextrous controls standard on modern Kel-Tec designs support mixed-handed teams and training environments. The tan finish provides subdued aesthetics suitable for various operational contexts while resisting fingerprints and corrosion, and the rifle's modular rail systems accommodate industry-standard tactical accessories including optics, lights, and furniture upgrades for mission-specific configurations.
