Firearms Manufacturers Trust Sirois Tool for Reliable and Consistent Tooling, Fixtures, and Gages

There is little room for error in the firearms industry. Whether it’s a smaller-scale manufacturer producing a few hundred custom firearms each year or a supplier producing extremely high volumes, every component must meet strict and precise specifications.
Behind that demanding level of consistency is a deeply reliable supply chain.
At Sirois Tool, we’ve spent decades supporting firearms manufacturers by producing the tooling, fixtures, and precision gages that help them maintain quality and bring new products to market. While we don’t manufacture firearms components themselves, our products help our customers produce those parts accurately and consistently.
Sirois Tool Supports a Range of Firearms Manufacturers
Sirois Tool is located in New England, the traditional home of firearms manufacturing, and offers decades of experience supporting companies throughout the industry. While our roots are in a region known for its rich firearms manufacturing history, we proudly serve firearms OEMs across the United States.
No matter a firearms company’s size or specialty, manufacturing processes are constantly evolving. Legacy products often require replacement fixtures and gages, while new product launches demand entirely new tooling. Additionally, production improvements create opportunities to redesign existing fixtures for longevity and better performance.
Firearms manufacturers need a trusted and agile supplier with deep experience and understanding of the industry to quickly produce specialized tooling and inspection equipment.
Experience Matters
Plenty of machine shops can manufacture a fixture or gage from a drawing. The difference comes from understanding the practical application of these tools.
Our team has deep experience producing both simple and complex tooling, fixtures, and gages for precision manufacturing environments. In addition to understanding how these tools are manufactured, we are uniquely familiar with how they’re used on our customers’ production floors.
Design for Manufacturability Improves Performance
While we are a made-to-print manufacturer, our experience frequently allows us to identify opportunities for improvement when customers request feedback.
For instance, we may recognize a feature that adds unnecessary manufacturing complexity or identify a design adjustment that could reduce production costs or improve the part’s performance. We might also suggest a more optimal material that’s been coated or heat treated to improve the gage or tool. Because we’ve manufactured similar tooling across a variety of applications, we often provide practical insights that help customers achieve their goals more efficiently. These conversations can result in:
- Shorter lead times
- Opportunities for reduced costs
- Reduced risk in manufacturing
These benefits can have a lasting impact, particularly in a critical industry like firearms manufacturing.
Precision Requires More Than Standard Machining Alone
It’s not enough for our firearms customers to meet tolerances; they also need confidence that those tolerances have been properly verified.
Many of the precision gages we manufacture are designed to inspect features with extremely tight tolerances. In fact, we must manufacture our gages to tolerances even tighter than the parts they’re checking, typically as tight as one-tenth of the part feature tolerance! Ensuring that level of accuracy often requires more than standard machining.
Virtually every tooling or gage project begins with milling or turning processes before moving into secondary operations. Our team has expertise in precision grinding, including surface, cylindrical, and jig grinding services, as well as sinker EDM and wire EDM services. These finishing operations allow us to achieve the tolerances and critical features required for high-precision tools, fixtures, and gages.
Because machining, grinding, and EDM operations are performed under one roof, our customers benefit from true single-source manufacturing solutions that simplify project management and help maintain quality throughout production.
Documentation and Traceability Are Critical
Sirois Tool maintains the following certifications and credentials:
- AS9100 Rev. D / ISO 9001:2015 certification
- ITAR registration
- CMMC Level 2 self-certification
These systems allow us to provide the documentation, material verification, inspection records, and process controls often required for highly regulated environments like firearms manufacturing.
