Why the RDB Defender Matters
The bullpup configuration delivers a compact overall length without sacrificing barrel length. The 16" pencil barrel provides velocity and accuracy while keeping the rifle maneuverable in tight spaces. The M-LOK handguard gives you genuine tactical flexibility—mount lights, lasers, or grips where you need them.
Downward ejection eliminates the traditional bullpup compromise of spent cases in your face or requiring ambidextrous operation. The collapsible stock adapts to different shooters and gear configurations.
This is a rifle built for those who take their defensive responsibilities seriously—whether protecting property, community, or home. The RDB Defender doesn't compromise on capability or versatility.
