The Kel-Tec RDB Hunter is a variant of the RDB series tailored for hunters, featuring a design that emphasizes practicality and efficiency for field use. It is chambered in .223 Remington/5.56mm NATO, which offers versatility for various hunting and shooting applications. The rifle has a 20.5" barrel that provides a balance of maneuverability and ballistic performance, essential for hunting scenarios where both are crucial. This model comes with a black synthetic stock and is equipped with a Picatinny rail on top for mounting optics, but it does not include built-in sights, allowing shooters to customize their sighting system according to their preferences. The overall length of the RDB Hunter is 30.4", and it weighs approximately 6.9 lbs, making it relatively lightweight and easy to handle during extended periods in the field. The RDB Hunter also features the series' characteristic downward ejection and fully ambidextrous controls, which are designed to offer convenience and ease of use for both left and right-handed shooters. The rifle uses a bullpup configuration, which contributes to its compact size while maintaining a longer barrel length for accuracy.
