Blackstone Arms LLC is a small company that is based on accuracy, quality and great customer service. We specialize in building AR platform uppers in 6.8SPC and 5.56. My name is Eric and I am the owner/operator of Blackstone Arms and I have a lifetime of experience with firearms and hunting. Blackstone Arms was started to offer a quality and accurate product without the high end price.

Each upper is hand assembled using high quality components, excellent craftsmanship and attention to detail. Every receiver is squared and all tolerances are checked to assure the best fit. All uppers built by Blackstone Arms are guaranteed to shoot 1 MOA with quality ammunition.
