This bullpup rifle is truly revolutionary thanks to the downward shell ejection system which eliminates the side ejection system typically found on other bullpup designs and is a product of forward thinking by the engineers at the Kel-Tec R&D division. Additional the RDB bullpup rifle features an adjustable system making it great to use with a wide variety of ammunition from .223 Remington up to 5.56 NATO.
Moreover the RDB can serve as an excellent host platform for individuals who already own a suppressor and wish to suppress the bullpup platform providing you with a short overall length rifle great for hunting or personal protection. The RDB is compatible with all standard pattern AR-15 magazines.
