The RDB Survival’s bullpup chassis puts the action behind the trigger, keeping overall length to just 26" without sacrificing ballistics from the 17.3" nitride-treated chromoly barrel. This layout enhances maneuverability in confined spaces and makes the rifle easy to stow in a pack or vehicle.
Kel-Tec’s downward-ejection system directs spent cases straight toward the ground, solving the common bullpup issue of brass interfering with the shooter. Combined with an ambidextrous paddle-style magazine release and centrally located cross-bolt safety, the rifle caters to both right- and left-handed users.
An adjustable short-stroke gas piston helps the rifle run clean while letting the shooter fine-tune operation for different ammunition or suppressor use. The 1:7" right-hand twist rate stabilizes a wide range of 5.56 NATO bullet weights, including heavier projectiles.
The glass-fiber-reinforced polymer frame, skeletonized twin-rod stock, and polymer handguard keep weight under 6 lb without sacrificing durability. A full-length top rail offers plenty of room for optics, and the included flip-up polymer sights provide an immediate aiming solution out of the box.
