Bullpup rifles have earned a place in modern tactical arsenals for compact footprint and maneuverability without sacrificing barrel length. For shooters who demand ambidexterity, unobstructed sight lines, and reliable feeding, a design that addresses traditional bullpup trade-offs is essential.
KELTEC RDB 
Why the KELTEC RDB stands out
The KELTEC RDB redefines bullpup functionality with 11 innovations that target common shortcomings. Chief among them is the downward shell ejection system that vents spent casings away from the shooter’s face and out of the line of sight, making the rifle truly ambidextrous for practical left- or right-handed operation. The platform’s adjustability for a wide variety of ammunition further broadens its utility for training, range work, and field use.

Downward ejection and ambidexterity
Downward ejection eliminates the side-ejection disadvantage of many bullpups—no more hot brass flicking past your cheek or optics. Combined with intuitive controls, the RDB lets shooters maintain consistent cheek weld and sight picture regardless of shooting stance or dominant hand.
Specifications shooters care about
Built around the .223Rem caliber, the RDB balances recoil management and ballistic performance for 5.56/.223-class ammunition. Key specifications: Barrel Length 20, Overall Length 30.6, Weight Unloaded 7.1lbs, Magazine Capacity 20 or any AR15 compatible magazine, Twist Rate 17, Trigger Pull 4lbs. These numbers translate to a long 20 barrel in a compact 30.6 package — favorable for velocity and practical accuracy without a long external profile. Price is competitive at $791.99 for a rifle that resolves many bullpup compromises.

Handling, trigger, and field use
The 4lbs trigger pull and 1:17 twist rate offer a balance for common .223 projectiles; combined with the RDB’s adjustable components, this produces predictable group behavior across loads. The acceptance of common AR magazines reduces logistics concerns for those who already run AR-pattern systems.
