Frequently asked questions

Don’t see your question? Request a quote and our engineering team will answer it.

Does Redstone make finished firearms?

No. Redstone machines firearms and defense components to your print. You supply the drawing and the material callout, Redstone produces the parts to tolerance with inspection and traceability. Assembly and any regulated finishing stay with you or your licensed partner.

Can parts be produced in the United States?

Yes. Redstone runs a domestic production option at the Seattle facility for programs that need parts machined in the United States. Certified overseas shops are also available when domestic production is not required. Redstone confirms the right facility for your program at the quoting stage.

What tolerances can Redstone hold on firearms components?

±0.005 inch standard, ±0.001 inch on critical features, and ±0.0005 inch on qualifying programs. Repeatability is verified across the production run with CMM, not just on the first article. Send your print and Redstone confirms the achievable tolerance at the feasibility review.

What inspection and traceability does Redstone provide?

Every new part gets a first-article inspection. Production shipments include a CMM dimensional report, material certification, and lot traceability records. Material and lot traceability is maintained for the life of the program and available on request.

Can Redstone re-source an existing firearms component program from another supplier?

Yes. Send the existing prints, FAI package, and current supplier quote. Redstone assesses the part, runs a parallel quote across domestic and certified overseas options, and projects landed-cost and lead-time impact before you commit. Existing fixtures and programs are often re-usable.
