Kel-Tec RDB Bullpup 5.56mm 17.3" Black

The Kel-Tec RDB: Bullpup Done Right

The Kel-Tec RDB represents a fundamental rethinking of bullpup rifle design. Where traditional bullpups eject casings to the side—creating problems for left-handed shooters and cluttering the shooter's field of view—the RDB ejects downward. This elegant solution makes the rifle genuinely ambidextrous and keeps your sight picture clear.
