The Kel-Tec RDB is a compact 5.56 NATO bullpup rifle designed for balanced handling and ambidextrous operation. Its distinctive downward-ejection system directs spent cases away from the shooter’s line of sight, while fully ambidextrous controls support use from either shoulder. The 20.5-inch barrel delivers a full-length rifle configuration without sacrificing the compact handling advantages of the bullpup layout. Integral MIL-STD-1913 Picatinny rails provide space for optics and accessories, and the rifle accepts widely available AR-15 pattern magazines. This configuration includes one 20-round magazine. A scope is not included.
