Kel-Tec RDB-C Bullpup Downward Ejecting .223 Remington 5.56 NATO Black Rifle

The Kel-Tec RDB-C is a compact bullpup rifle chambered for both .223 Remington and 5.56 NATO. Its 20.5-inch barrel delivers a full-length rifle configuration while the action and magazine remain positioned behind the trigger, producing a shorter overall package. The downward-ejection system directs spent cases below the rifle, making the layout suitable for right- or left-handed operation. This model features a fixed synthetic stock, black finish, ambidextrous manual safety, standard sights, and a top Picatinny rail for mounting an optic.
