Kel-Tec RDB Bullpup 5.56mm Tan 17.3" Barrel

The Kel-Tec RDB: Redefining the Bullpup Platform

The RDB stands for Rifle Downward-ejecting Bullpup—and that name tells you everything about what makes this rifle different. Kel-Tec has engineered a 5.56mm bullpup that breaks the mold of traditional compact rifle design.

Ambidextrous by Design

Unlike conventional bullpups that eject brass to the side, the RDB's patented downward-ejection system sends spent casings straight down through the stock behind the magazine well. This means left-handed and right-handed shooters enjoy equal comfort—no more hot brass or gas in your face. The reversible charging handle and intuitive safety further cement the RDB's ambidextrous credentials.

Accuracy and Handling

The 17.3" barrel features a 1:7 twist rate optimized for 5.56mm ballistics, delivering genuine accuracy in a package that measures just 27.3" overall. At 6.7 pounds unloaded, the RDB remains manageable for shooters of all sizes. The high-impact Zytel forend with integrated Picatinny rail provides a solid platform for mounting optics and accessories.

Superior Trigger Performance

Bullpup triggers have a reputation for being problematic. Kel-Tec solved this with a smooth, well-tuned trigger system featuring a clean break and predictable take-up. The 4.5 to 5.5-pound pull is competitive with quality AR-15 rifles.
