About this product
The Keltec RDB-S is a compact, semi-automatic bullpup rifle chambered for .223 Remington/5.56 NATO designed for survival and backcountry applications. Its bullpup layout preserves a full-length barrel in a shorter overall package for improved maneuverability. The design is fully ambidextrous thanks to a patented downward-ejection system and reversible controls. An adjustable gas piston and a refined trigger help maintain reliable operation across varied loads and accessory configurations.
