Product Description

Like no ordinary bullpup, the RDB series of rifles redefines the platform. You've never experienced balance or a trigger quite like this in any other design. The RDB is completely ambidextrous due to its patented downward-ejection, magazine catch/release placement, intuitive safety and reversible operating handle. The RDB series of bullpups delivers a 5.56/.223 ballistic advantage in a very compact package that's easy to manipulate for just about anyone. The RDB's 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. 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. 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.
