Kel-Tec RDB20BLK RDB 5.56 NATO 20.5" 21-Round Bullpup Rifle

The Kel-Tec RDB20BLK RDB 5.56 NATO 20.5" 21-Round Bullpup Rifle delivers modern tactical efficiency in a compact, ergonomic platform built for operators who demand accuracy without sacrificing portability. Bullpup design shifts the action rearward, creating a shorter overall length while maintaining a full rifle barrel, making this platform ideal for close-quarters engagements, vehicle operations, and confined-space tactical deployments. Law enforcement and military units have long appreciated the bullpup configuration for its balance of firepower and handling in dynamic environments where traditional rifle length becomes a liability.

At 13 pounds with a 20.5-inch barrel, the RDB20BLK achieves combat-ready weight and dimensions of 37.5 inches overall length, enabling quick target acquisition without fatigue during extended operations. The 21-round capacity magazine feeds proven 5.56 NATO ammunition, the NATO standard cartridge with reliable performance across tactical, training, and defensive applications. The RDB's design features a gas-piston operation system that cycles cleanly and consistently, reducing carbon fouling in the receiver and extending maintenance intervals—a critical advantage in field conditions where cleaning supplies may be limited.

This rifle suits active shooters, tactical competitors, and firearms enthusiasts seeking a purpose-built platform for precision shooting and rapid follow-up rounds in compact environments. The bullpup ergonomics benefit shooters who operate in vehicles, structures, or tight formations, where conventional rifle profiles create handling challenges. The Kel-Tec RDB20BLK integrates with standard 5.56 NATO ammunition and AR-platform optic mounting systems, allowing shooters to outfit the rifle with proven accessories and maintain compatibility with existing ammunition supplies and tactical gear ecosystems.
