AXTS’s A-DAC is a nifty lower receiver for the AR-15. What differentiates it from standard mil-spec lower receivers is that the magazine release button, along with releasing the magazine, manipulates the bolt catch. Why would you want this feature? It makes clearing malfunctions much faster. This video demonstrates the advantages of the system…

Only one extra part, a small internal pin, is added to the receiver. This allows full compatibility with AR-15 upper receivers.

AXTS Weapon Systems have not yet posted pricing on their website.
