The Approach
How a Build Moves
Every engagement begins with specification and ends with documentation. Compliance is treated as part of the craft, not a separate department.
- 01
Specification and Consultation
Every build starts with a direct conversation about specification, materials, and manufacturability. We work through what you need before any metal moves, whether you want a single custom build or a small production run.
- 02
Design and Prototype Development
Where the engagement calls for it, we develop and refine a prototype against the agreed specification. Custom work is validated against the requirements before a production run is committed.
- 03
Production to Specification
Custom assembly and manufacturing under FFL, conducted in compliance with federal, state, and local regulation. The build follows the approved specification, not a generic template.
- 04
Quality Control and Documentation
Quality control documentation and ATF compliance integration are part of the deliverable. Every firearm is built to be inspected, documented, and trusted. Records and accountability are not an afterthought.
- 05
Delivery to a Licensed Facility
Finished firearms are delivered to your FFL or licensed facility. We do not run a consumer checkout for manufactured orders; delivery goes through licensed channels.
Licensing and approach
Federally Licensed
Federal Firearms License (FFL), Active and Licensed, plus licensed dealer authority. Ferrum Arms LLC is a federally licensed manufacturer and dealer of firearms and firearm components, operating in compliance with all federal, state, and local regulations.
Built, Not Branded
Iron over image. The work speaks louder than the branding. Every build is carried through with accountability as part of the deliverable.
Built for Inspection
Documentation is part of the work, not an afterthought. Records and accountability are part of what we deliver.
