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

The Kel-Tec RDB Defender in tan is a compact, innovative 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 downward ejection system makes it fully ambidextrous — spent casings eject straight down, eliminating brass-in-the-face concerns for left- or right-handed shooters alike.

Built around a semi-automatic, gas-operated action, this modern sporting rifle features a 16.1-inch barrel and accepts standard AR-15/STANAG magazines, so you can use the mags you already own. The aluminum M-LOK handguard provides a solid, lightweight platform for mounting lights, lasers, foregrips, and other accessories. The tan synthetic stock keeps the overall package light at just 6.4 lbs, while the blued metal finish on the black receiver components adds durability and a clean contrast.
