Kel-Tec RDB Bullpup 5.56x45mm NATO 17.3" Blued Threaded Barrel Tan

The Kel-Tec RDB Defender is a semi-automatic bullpup rifle chambered in 5.56x45mm NATO and listed as compatible with 223 Remington. Its downward shell ejection port directs brass and gas away from the shooter's line of sight, and the controls are ambidextrous, so the rifle can be operated from either shoulder.

The rifle has a 17.3-inch blued barrel with a 1:7 twist and 1/2x28 threads for attaching a muzzle device or suppressor. It weighs 6.7 pounds, measures 27 inches overall, and is built with an aluminum frame in a tan finish. It has no iron sights and includes a 1913 Mil-Spec Picatinny rail for optics. The 20-round capacity is supported by standard magazines, and any AR-15 compatible magazine can be used.
