The Battle arms development 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-IC is also skeletonized to reduce weight.
