Kel-Tec RDB Defender 5.56 NATO Bullpup Rifle – 16.1″ Barrel, 20-Round, M-LOK, Tan

The Kel-Tec RDB Defender in Tan is a compact, innovative semi-automatic bullpup rifle chambered in 5.56 NATO / .223 Rem, engineered for shooters who demand maximum maneuverability without sacrificing barrel length. At just 26.1 inches overall, the RDB Defender’s bullpup configuration places the action behind the trigger, delivering a full 16.1-inch barrel in a remarkably short package — perfect for home defense, range use, and tactical applications.

One of the RDB’s most distinctive features is its downward ejection system, which eliminates spent casings from the shooter’s field of view and makes the rifle equally comfortable for left- and right-handed users. It accepts standard AR-15/STANAG magazines, giving you broad compatibility and easy access to affordable, widely available magazines — including the included 20-round mag.

The aluminum M-LOK handguard provides a lightweight, heat-resistant platform for attaching your preferred accessories, from foregrips and lights to laser systems and bipods. The synthetic tan stock offers a rugged, weather-resistant build with a modern look, while the blued black metal finish adds durability and corrosion resistance. Weighing in at just 6.4 lbs, this bullpup is easy to handle in dynamic shooting scenarios.
