Kel-Tec RDB 5.56x45mm NATO 20.50" 20+1 Black Semi-Auto Bullpup Rifle

The Kel-Tec RDB (Rifle, Downward-ejection, Bullpup) is a semi-automatic bullpup rifle chambered in 5.56x45mm NATO and engineered around Kel-Tec's signature downward-ejection system. Instead of ejecting spent casings out the side, the RDB drops them straight down through a chute in front of the trigger guard, allowing a fully ambidextrous layout with no ejection-port concerns for either shoulder.

The 20.50" barrel features a 1:7" twist for reliable stabilization across a wide range of bullet weights and is finished off with a flash hider at the muzzle. The rifle ships with a 20-round detachable magazine for a 20+1 capacity, and the lower accepts standard AR-15-pattern magazines so users can swap in their preferred AR-15 mags.

The bullpup configuration places the action behind the trigger group, packing a full-length barrel into a compact package measuring 30.60" overall and weighing 7.20 lbs unloaded. The fixed bullpup stock and polymer receiver are finished in black, with the metal components receiving a durable Black Nitride finish. Controls - including the safety, magazine release, and bolt - are mirrored for fully ambidextrous operation, and the polymer grip keeps the center of gravity close to the shooter's support hand.

The receiver is topped with a Picatinny optics rail and ships optic ready, ready to mount the shooter's preferred red dot, low-power variable, or magnified scope. Purpose-built for hunting and target use, the RDB combines a balanced bullpup layout, downward ejection, and modern ambidextrous controls into a compact, user-friendly 5.56mm platform.
