Features:
- Downward Ejection-This unrivaled design sends spent brass downward through the stock behind the magwell making it a truly ambidextrous bullpup rifle. Gone are the days of hot gas & brass flying out of a side-ejection port… you’re welcome southpaws.
- Unparalleled Trigger System-Bullpup triggers are notoriously bad so we tackled that issue head on and won. This trigger is incredibly smooth with a nice take-up and clean break. Combined with a 1:7 twist barrel all RDB models offer excellent accuracy.
- ADJUSTABLE GAS SYSTEM-All of the RDB models operate off of the same adjustable gas piston system. This feature allows the user to tailor the bolt carrier speed to eliminate excessive recoil while running a suppressor and ensure reliability for various loads.
