The Kel-Tec RDB20 is a downward-ejecting bullpup rifle built around a 20 inch barrel and chambered for .223 Rem / 5.56 NATO. Its bullpup layout places the action behind the trigger so shooters retain a full-length barrel in a compact overall package. The design is fully ambidextrous with downward ejection and accepts standard AR-15 magazines. An adjustable gas piston system helps tailor operation for different loads and suppressor use.
