The Kel-Tec RDB 20″ 5.56 Bullpup Rifle is a precision-focused semi-automatic rifle that combines full-length ballistic performance with a highly compact bullpup design. Chambered in 5.56x45mm NATO, it delivers reliable power, excellent accuracy, and modern tactical versatility in a streamlined platform.

At the core of this rifle is its 20-inch barrel, which maximizes velocity, accuracy, and long-range capability while still maintaining a shorter overall footprint than traditional rifles. This makes it ideal for users who want full rifle performance without sacrificing maneuverability.

A defining feature of the RDB platform is its patented downward ejection system, which directs spent casings safely below the firearm. This eliminates side ejection entirely, making the rifle fully ambidextrous and comfortable for both right- and left-handed shooters. Combined with intuitive controls and a reversible operating handle, the design prioritizes accessibility and ease of use.

The bullpup configuration shifts the action rearward, significantly reducing overall length while maintaining barrel length. This improves balance and handling, especially in confined environments or dynamic shooting situations.

Finished in Flat Dark Earth (FDE), the rifle offers a durable and modern tactical appearance. The semi-automatic action ensures consistent cycling and dependable performance across a variety of shooting applications.

The Kel-Tec RDB 20″ 5.56 Bullpup Rifle stands out as a refined evolution of the bullpup concept, offering full-length performance, compact ergonomics, and true ambidextrous usability in one innovative package.
