The Jacob Grey Billet 7075 Aluminum Stripped Upper Receiver is a step above the rest! When you choose a Jacob Grey Upper Receiver you get better than Mil-Spec quality with the features you want. The Jacob Grey JG-15 UR 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. The forward assist commonly found on most cast and forged upper receivers was originally intended to help with the bcg jamming and sticking issues found with lesser quality upper receivers. With Jacob Grey’s thicker more rigid walls, and sleek sides, the need for forward assist is no longer there. Use your Jacob Grey JG-15 Upper receiver on your next build, or if you’re looking for the ultimate in fit and finish, check out our matching JG-15 Lower Receiver and complete the set. And for the home enthusiast or professional our unfinished JG15 Billet Aluminum upper receiver is the perfect choice for your very own finish.
