The KelTec RDB 5.56 NATO 17" Bullpup Rifle (KelTec part no. RDBBLK) redefines the bullpup with a downward shell-ejection system that eliminates the side-ejection disadvantage found on most competing designs, sending brass and gas out and away from the shooter’s line of sight and off-side face. That makes the RDB genuinely ambidextrous and comfortable to shoot from either shoulder. Its compact 17-inch barrel keeps overall length short for maneuvering in tight spaces, and the design is well suited to hosting a suppressor thanks to its adjustable gas system.
