About Us

80% Arms is dedicated to providing the highest quality 80% lowers and jigs on the market. Sometimes when you want something done perfectly, you just have to build it yourself. That's just what we did when we designed our jigs and lowers from the ground up to include all the features we believe are necessary to build a great product.

Our products are precision machined on state of the art American made 5-axis CNC machines in our manufacturing facility in Orange County, CA. We only use premium aluminum made in the USA; it costs more than Chinese aluminum, but the perfect lower would not be perfect if we used inferior materials.

We take great pride in our products and adhere to the strictest quality control practices in the industry. We’re constantly innovating and looking for ways to support the 80% community.

Our shop foreman is a Marine with multiple tours of duty in Desert Storm and Panama and more than 20 years of metallurgy and CNC experience. Our technical support manager is also a Marine with combat experience in both Iraq an Afghanistan. Why does this matter? Because while engineers design products, it’s the folks on the front line that know what works and what doesn’t. That experience goes into our design and testing to ensure our products will meet and exceed your expectations.
