Our Assessment:  The Kel-Tec RDB Hunter is a specialized variant of the innovative RDB series, tailored specifically for the hunting community. It retains the hallmark bullpup configuration of the original RDB, where the action and magazine are behind the trigger group, resulting in a compact firearm with a longer barrel. This design is ideal for hunting, offering improved maneuverability without sacrificing accuracy, crucial for long-range shooting. The Hunter model typically features a barrel length of around 20 inches, optimizing it for the precision required in hunting scenarios. Additionally, it is chambered for the 5.56×45mm NATO cartridge, balancing power and manageable recoil, and is compatible with standard AR-15 magazines, ensuring ease of ammunition availability.

A key feature of the RDB Hunter is its downward ejection system, which ejects spent cartridges downwards from behind the magazine well. This unique design makes the rifle ambidextrous, allowing comfortable use from either shoulder, an essential feature for diverse shooting positions in hunting. The rifle’s adjustable gas piston system further enhances its appeal, allowing shooters to tailor the rifle’s performance for different types of ammunition or environmental conditions, while also maintaining a cleaner action by keeping propellant gases and fouling out of the receiver. Designed with hunters in mind, the RDB Hunter incorporates features like a streamlined forend and a comfortably designed stock, facilitating ease of use during prolonged periods of aiming. The inclusion of a Picatinny rail for mounting scopes and other hunting accessories further adds to its versatility, making the Kel-Tec RDB Hunter an ideal choice for those seeking a compact, accurate, and adaptable hunting rifle.  Please see our photos and good luck on your bid! -L.S.
