The Jacob Grey Ultralight Rifle was designed with the next generation AR15 in mind. This AR15 rifle is built around the 7075-T6 billet lower receiver specifically machined and cut in areas where excess material was unnecessary and areas that see excess use and wear, reinforced and strengthened to give a sleek, refined look, without losing the classic lines of the AR15 platform. The same consideration was given to the matching billet upper receiver.
