The Jacob Grey Ultralight Lower Receiver was designed with the next generation AR-15 in mind. This 7075-T6 billet lower receiver is 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 AR-15 platform.

The Jacob Grey JG-15 Ultralight Lower Receiver is manufactured using 7075 T6 aluminum alloy, 7075 is 65 % stronger than the widely used 6061 alloy used in most other manufacturers’ billet uppers. That choice 7075 billet is machined with advanced technology 5-axis machines to produce uppers that will outperform the competition with greater strength, accuracy, and durability, even under the stresses of long-term semi and full-automatic shooting. Use your Jacob Grey JG-15 Ultralight Lower Receiver on your next build, or if you’re looking for the ultimate in fit and finish, check out our matching JG-15 Ultralight Upper Receiver and complete the set.
