Xavier Gonzalez

Founder, President and CEO GSI International Inc.

Last Reviewed: September 18, 2026

Executive Summary

Xavier Gonzalez founded GSI International in 2000 and has run it as president and chief executive ever since. The company is a precision CNC machining and fabrication shop in Chandler, Arizona, offering milling, turning, fabrication, finishing and final assembly in aluminium, stainless steel and steel, and it is also something more specific: the leading supplier of bullet feeders and reloading accessories for Dillon Precision’s progressive reloading presses. That combination is not accidental. Gonzalez spent roughly two decades in product design and development at Dillon Precision before starting GSI, and the products he is best known for are the ones he was uniquely placed to design — feed systems, trim dies and feed chutes that make high-volume ammunition reloading faster and more reliable on machines he knew intimately.

Professional Journey

Gonzalez’s career began inside the reloading equipment industry rather than adjacent to it. He spent about twenty years at Dillon Precision, the Arizona manufacturer whose progressive presses are the standard equipment for high-volume ammunition reloading, working in product design and development. That is an unusually long apprenticeship in a narrow discipline, and it left him with detailed knowledge both of the machines themselves and of what their users were still doing by hand.

In 2000 he left to start GSI International in Chandler, Arizona, describing the move as a way to channel his own drive to innovate rather than as a break with the industry. The company was built as a precision machining and fabrication business — CNC milling and turning, fabrication, finishing and final assembly — and Gonzalez assembled a team of engineers, programmers and technicians around it, with the company describing its collective product design and manufacturing experience as spanning more than forty years.

The distinctive part of the business is its own branded product line. GSI designs and manufactures bullet feeding systems for Dillon’s XL 650 and 1050 presses, along with trim dies, ammunition feed chutes and cable management hangers, all made in the United States. The bullet feeder is the product that put the company in front of the wider shooting public: it was shown at SHOT Show 2017 and reviewed in the NRA’s American Rifleman, and GSI is now described in the trade press as the leading supplier of bullet feeders and reloading accessories for Dillon machines.

Alongside that, the shop takes on custom machining work across the firearm, custom automotive and aerospace sectors, producing machined parts and components to customer specification. The company has operated continuously from Chandler since 2000, holds ISO 9001:2015 certification, and remains privately held with no disclosed outside investment.
