Are your production facilities certified?

The production facilities are ISO 9001 certified. Redstone provides U.S. engineering oversight and manages quality documentation on your behalf. Tell us your program's specific quality and inspection requirements at the quote stage so we can confirm fit before any work begins.

Do you take on military or ITAR-controlled work?

No. We produce commercial firearms components and confirm regulatory fit at the quote stage. We do not take on ITAR-controlled or military programs. Share the nature of your part and program at the quote stage and our team will confirm whether it is a fit for our production model.

How do you control quality on safety-critical features?

We hold critical and mating features with CMM verification, run first-article and in-process inspection, and provide dimensional reports on every batch. Material certifications and full lot traceability ship with every order, with a Certificate of Conformance.

Which processes and materials do you use?

Precision CNC machining, investment casting, and metal injection molding, in materials including carbon and alloy steels, stainless steels, aluminum, and titanium, with finishing to specification. Our engineering team recommends the process that fits your part at the feasibility review.

What volumes do you run?

We are built for recurring production volume rather than one-off prototypes. We will confirm at the quote stage whether your annual volume is a fit and recommend the most cost-effective process.

How do you manage quality across the program?

First-article inspection, in-process checks, and dimensional reports on every batch, with a Certificate of Conformance on every shipment. Third-party inspection is available on request.
