Kel-Tec RDB 5.56mm NATO 17in Green Anodized Semi Automatic Modern Sporting Rifle - 20+1 Rounds - 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. The RDB series of bullpups delivers a 5.56/.223 ballistic advantage in a very compact package that's easy to manipulate for just about anyone. This variant is the original and features a high-impact resistant Zytel forend with built-in Picatinny-style rail on the bottom for mounting accessories.
