A truly ambidextrous bullpup.
Kel-Tec’s RDB-C is a modern, state-compliant take on the traditional bullpup concept. Since its inception, the bullpup category has been described with having a pistol grip mounted ahead of the magazine, which allows engineers to design a very compact firearm without compromising barrel length. Such a definition describes Kel-Tec’s RDB (Rifle, Downward-Ejecting, Bullpup), which revolutionized this market in 2010. But you won’t find that it applies to the RDB-C because it lacks a pistol grip.
When the bolt body reaches its most rearward position, a pair of spring-powered ejectors strike the case and propel it downward through the aluminum-lined ejection port toward the shooter’s feet.
How does the RDB-C operate? For starters, there’s an adjustable in-line, short-stroke gas piston system. The valve is positioned above the RDB-C’s 20½-inch barrel. The rifle utilizes a seven-lug bolt with the extractor located at the 6-o’clock position to feed and clear the action. When the bolt body reaches its most rearward position, a pair of spring-powered ejectors strike the case and propel it downward through the aluminum-lined ejection port toward the shooter’s feet. The return spring shoves the bolt forward and strips another round from the top of the magazine and shoves it into battery.
There’s a charging handle located on the left side of the RDB-C near the adjustable gas valve, but its position can be swapped for lefties. When the handle is pulled rearward, it locks into place when engaging a small cutout. As you change magazines, you can either press the bolt-release button or slap the handle down to send the bolt assembly into battery.
