The KelTec RDB is a distinctive bullpup design built around a downward-ejecting mechanism to enable compact handling in a lightweight package. Shooters will find it suitable for range work and other situations where a short overall length and ambidextrous controls are desirable.

Constructed with a high-impact resistant Zytel forend and an ergonomic layout, the RDB emphasizes modularity and user adaptability. The forend includes a built-in Picatinny-style rail on the bottom for mounting accessories, and the rifle is offered in a green/black finish in some listings.
