The Kel-Tec RDB Defender is the result of taking the RDB and the RDB Survival and mashing them up to forge the perfect 5.56, light-duty, tactical bullpup. Lightweight, it comes standard with an aluminum M-LOK handguard, collapsible stock and 16″ pencil profile barrel, delivering exceptional maneuverability in a short 27″ overall length while maintaining full-power 5.56x45mm NATO performance.
What truly sets the RDB Defender apart is its patented downward ejection system that supports true ambidextrous use, keeping spent brass directed away from the shooter while allowing shoulder transitions without disruption. The trigger is incredibly smooth, with a nice take-up and clean break. Combined with a 1:7 twist barrel, all RDB models offer excellent accuracy. The RDB is completely ambidextrous due to its patented downward-ejection, magazine catch/release placement, intuitive safety, and reversible operating handle.
All RDB models operate off of the same adjustable gas piston system. This feature allows the user to tailor the bolt carrier speed to eliminate excessive recoil while running a suppressor and ensure reliability for various loads. Chambered in 5.56x45mm NATO and compatible with AR-15 magazines, it offers a reliable defensive package built for property protection and versatile everyday readiness. The included 20-round Magpul PMAG and M-LOK handguard provide solid foundational versatility for tactical configuration.
