Get the Kel-Tec RDB Defender OD Green Rifle from BattleHawk Armory! 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. The trigger is incredibly smooth, with a nice take-up and clean break. 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. 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.
