Kel-Tec RDB17 5.56 NATO

The Kel‑Tec RDB17 is a compact bullpup semi-automatic rifle chambered in .223 Rem / 5.56x45mm that emphasizes ambidextrous handling and compact ergonomics for range and utility use. Its design routes spent cases downward through the stock behind the magazine well, keeping ejection out of the shooter’s line of sight. The adjustable gas piston system supports reliable operation across a variety of loads and makes the platform a suitable suppressor host.

The RDB17 combines a tan synthetic bullpup stock with blued metal components and an integrated top rail for optics. Controls are configured to be ambidextrous, and the rifle includes a refined trigger feel, an intuitive magazine release, and ergonomic lines for maneuverability and balance.
