Military and defense equipment demands more from its components. Dimensional tolerances are critical for fit requirements, and the supply chain behind those parts has to be reliable, documented, and traceable. Richardson Metals produces custom aluminum extrusions for defense contractors, accessory makers, and OEM equipment manufacturers. As one of the few precision aluminum extruders in the U.S. specializing in small parts, we can achieve tight-tolerance extrusions for fit-critical firearm components.

Extrusion Capabilities for Defense-Grade Components
Defense applications do not tolerate loose tolerances or inconsistent material properties. At Richardson Metals, we run precision and ultra-precision extrusions for defense-grade components, specializing in small-part precision. We engineer our profiles to meet exacting specifications, including:
- Tolerances held to ±0.001 inches on critical dimensions.
- Minimum wall thicknesses of 0.020 inches for lightweight structural components.
- Minimum circumscribed circle sizes up to 4.0 inches.
- JIT delivery programs for recurring customers.
We frequently extrude 6061 aluminum for structural components. This alloy delivers high strength, exceptional weldability, and excellent fatigue resistance. For cosmetic applications, we work with alloys like 6063. This provides a smooth finish for anodized receivers and handguards and holds tight cosmetic tolerances.
Common Defense Profile Types
Law enforcement and tactical equipment in particular rely on profiles that meet precise dimensional and interface requirements. At Richardson Metals, we regularly produce:
- Picatinny rail extrusions and accessory rails for tactical mounting systems.
- Aluminum handguard extrusion profiles, including custom hollow geometries.
- Receiver sub-profiles and structural blanks for machined components.
- Suppressor and enclosure housings utilizing round and non-round hollow profiles.
- Structural equipment frames for mobile platforms.
As a precision defense aluminum extrusion manufacturer, we review every geometry up front. If a design challenges standard extrusion limits, our engineers develop workable alternatives in order to supply the highest quality aluminum extrusions for high-stakes applications.
Surface Finishing & Compliance
Tactical components may require surface finishing to resist corrosion, prevent wear, and maintain optical profile control. We coordinate full finishing services through our qualified partners, including Type II clear or color anodizing for standard cosmetic protection. For high-contact surfaces, we specify Type III hard anodizing to maximize abrasion resistance. We also coordinate painting, powder coating, silk screening, and polishing in line with specific requirements.
We operate a fully RoHS and REACH-compliant facility and are able to supply complete quality documentation upon request. This includes our quality manual and detailed process inspection records covering raw material intake, processing, final inspection, and outgoing packaging. We hold active memberships with the Aluminum Extruders Council (AEC), the Aluminum Association, and the Precision Machined Products Association (PMPA).
Why Work With Richardson Metals?
At Richardson Metals, we offer defense aluminum extrusion with true precision small-part capability. While most large extruders reject tight-tolerance aluminum extrusions below massive volume thresholds, we welcome this exact work.
We serve the aerospace, defense, and electronics sectors, offering direct engineering support from concept through production. When profiles require complex holes, threads, or machined features, our sister company, Accudyne Corp, handles the CNC machining.
If your program requires a complex Picatinny rail extrusion aluminum mount, a lightweight aluminum handguard extrusion, or any other custom aluminum extrusion defense profile, we’re ready to help.
