Kel-Tec RBDCGRN: Like no ordinary bullpup, the RDB series of rifles redefines the platform. You\'ve never experienced balance or a trigger quite like this in any other design. The RDB is completely ambidextrous due to its patented downward-ejection, magazine catch/release placement, intuitive safety, and reversible operating handle. All of the 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. This variant is the original and features a high-impact resistant Zytel forend with a built-in Picatinny-style rail on the bottom for mounting accessories. Like all the RDB variants, it's completely ambidextrous, accurate, and compact. This model is California Compliant.
