We Build Things That Work.
GSI International has been designing and manufacturing precision parts, reloading accessories, and custom assemblies in Chandler, Arizona since 2000.
GSI started by someone who spent 20 years making it better.
Before founding GSI International, Xavier Gonzalez spent two decades in product design and development at Dillon Precision, one of the most respected names in the reloading industry. In 2000, he channeled that experience into something of his own.
The goal was straightforward: build a company where engineering expertise and manufacturing quality were never negotiated away. That standard has guided every product and every customer order since day one.
Today GSI International is a precision‑driven manufacturing partner
specializing in high‑reliability CNC machining, mechanical assemblies, and
mission‑critical components for military and industrial applications. With a
20‑year track record, advanced inspection capabilities, and a team
committed to craftsmanship and quality, we deliver consistent performance
across every project. From prototype to production, our focus is simple:
dependable parts, responsive service, and long‑term partnerships built on
trust. Everything ships from the same floor in Chandler.
The people behind the parts.
Our staff brings over 40 combined years of product design and manufacturing experience.
Engineers, CNC programmers, machinists, and technicians work side by side to deliver parts that meet spec, on time, every time.
ISO 9001:2015 Certified.
Quality is not a department at GSI International. It is built into every step of our process, from incoming inspection to final assembly. Our ISO 9001:2015 certification means every part we produce is governed by a documented system that ensures consistency, traceability, and continuous improvement.

OUR VALUES
MADE IN THE USA
Every hard part we manufacture is produced right here in Chandler, Arizona. We are not an importer. We are a manufacturer.
PRECISION FIRST
We use SolidWorks CAD and Mastercam CAM software to design and program every part we produce. Precision is not an option. It is the standard.
BUILT TO DELIVER
Whether we are running a prototype or a full production order, our commitment to on-time delivery and consistent quality does not change based on the order size.
