From its exceptional balance to its remarkably refined trigger, the RDB offers a shooting experience unlike anything else in its class. Thanks to Kel-Tec's patented downward-ejection system, along with an intuitive safety, ambidextrous magazine release, and reversible operating handle, the RDB is truly fully ambidextrous-comfortable and efficient for shooters of any dominance. The result is a compact rifle that delivers the ballistic performance of 5.56 / .223 in a platform that's easy to handle and manipulate for a wide range of users.The Kel-Tec RDB Defender takes the best elements of the RDB and RDB Survival models and blends them into a highly versatile, light-duty tactical bullpup. Lightweight and maneuverable, it comes standard with an aluminum M-LOK handguard, a collapsible stock, and a pencil-profile barrel, creating a streamlined rifle optimized for adaptability and control. Purpose-built for tactical flexibility and everyday readiness, the RDB Defender stands out as one of the most versatile bullpup rifles available today.
