Kel-Tec RDB Black 5.56NATO/223Rem 17.3″ Barrel 20+1



Product Name Kel-Tec RDB Black 5.56NATO/223Rem 17.3″ Barrel 20+1
Brand Keltec
Caliber 223 Remington/5.56x45mm NATO
Action Semi-Automatic
Barrel 15.00″ – 17.99″


The Kel-Tec RDB Black is a lightweight, semi-automatic, bullpup rifle with a 17.3″ barrel, Picatinny rails, and an exceptional trigger. The RDB (Rifle, Downward-­Ejecting, Bullpup) chambered in 5.56Nato/223REM uses a clean running, adjustable short stroke gas piston system for reliability with all types of loads even under adverse conditions.

Thanks to its bullpup configuration, the RDB packs a 17.3″ barrel within a short and lightweight 27.3″ rifle that balances at the trigger for fast handling in close quarters. The RDB sports an ambidextrous bolt release, a swappable charging handle, and features a downward ejection port,  making it extremely left hand friendly.

While many have come to love the advantages of the bullpup configuration, most would agree that a common area of disappointment is the trigger and this is where the Kel-Tec really shines. The RDB-S  boasts a light and crisp trigger that is rated at 4-6 pounds but has been tested much lighter (your mileage may vary) helping to keep your sights on target when the trigger breaks. The RDP is equipped with a NATO standard, AR style, 20 round MAGPUL magazine and it will accept any capacity STANAG magazine.
