KelTec RDB .223 Remington/5.56 NATO Rifle, Bullpup, Downward Ejection

The KelTec RDB is a semi-automatic bullpup rifle chambered for both .223 Remington and 5.56 NATO. Its 17.3-inch barrel and compact 27.75-inch overall length make it practical when maneuverability matters, while the downward-facing extraction system ejects spent cases below the rifle rather than to either side. The fully adjustable piston system allows the rifle to be tuned for different ammunition types and shooting conditions. A 20+1 capacity, ambidextrous manual safety, synthetic stock, top accessory rail, and threaded barrel complete this versatile black rifle configuration.
