KELTEC RDB

Overview

The KELTEC RDB is a bullpup semi-automatic chambered in .223Rem that integrates 11 innovations to address common shortcomings of traditional bullpup designs. Most notable is the downward shell ejection system, which directs casings away from the shooter’s face and eliminates side-ejection limitations—making the platform truly ambidextrous for left- and right-handed users.
