The BATTLEARMS DEVELOPMENT, INC BAD-EBC (enhanced bolt catch) was designed to be a drop-in upgrade to the existing MIL-SPEC bolt catch. Due to the design of this bolt catch, it provides not only a better purchase on the release portion but the lock portion of the catch as well. This makes reloading the gun from bolt lock much faster and locking the bolt to the rear much easier. The BAD-EBC is also skeletonized to reduce weight and remove material not needed.
