Kel-Tec RDB Defender 5.56 NATO 20" Bullpup Semi-Auto Rifle Tan

The Kel-Tec RDB Defender is a semi-automatic bullpup rifle chambered in 5.56x45mm NATO and 223 Remington. Its downward ejection port directs spent brass and gas away from the shooter's line of sight, which makes the rifle usable from either shoulder.

The rifle has a 20-inch barrel with a 1:7 twist and 1/2x28 threads for muzzle devices or a suppressor. It has an aluminum construction, a 6.7-pound weight, and an overall length of 27 inches. The 20-round magazine capacity is listed, and the rifle is also said to accept AR-15 compatible magazines. It has no iron sights and includes an integrated 1913 Mil-Spec Picatinny rail, a 4-pound trigger pull, an ambidextrous magazine release, and an adjustable gas system.
