Precision CNC Machining for Weapons Systems

Weapons system components demand zero-defect machining, mil-spec materials, and full documentation. A fire control housing with a bore that is off by 0.002 inches can cause a weapons system malfunction. We machine 7075-T6 aluminum, 4140 and 4340 hardened steel, and 17-4 PH stainless to tolerances as tight as ±0.0005 inches. Every order ships with CMM reports, material certs, and DFARS-compliant traceability.

1

Mil-Spec Materials

We source and machine 7075-T6 aluminum, 4140/4340 steel, 17-4 PH stainless, and titanium 6Al-4V — all with DFARS-compliant mill certs and heat lot traceability.

2

Critical Tolerances

We hold ±0.001" on general features and ±0.0005" on critical bores, pin holes, and mating surfaces. Every part is CMM verified before shipping.

3

Defense Documentation

Dimensional inspection reports, material certs, and process records. We document to MIL-STD requirements and provide what your quality team needs for program compliance.

Serving the US Defense Weapons Industry

The US defense industry is the largest in the world, with major prime contractors and thousands of Tier 1 and Tier 2 suppliers manufacturing weapons systems for every branch of the military.

From infantry small arms to crew-served weapons platforms, every system depends on precision-machined components held to MIL-STD specifications with full material traceability and DFARS compliance.

Whether your team is developing next-generation weapons systems or supporting sustainment programs for legacy platforms, we machine the parts you need with the documentation your program requires.

Lockheed Martin — Defense Prime

Largest defense contractor globally. Small arms, guided munitions, and integrated weapons systems programs driving demand for precision-machined components.

General Dynamics — Ordnance & Tactical

A major manufacturer of crew-served weapons, ammunition, and ordnance systems requiring tight-tolerance machined components and full documentation.

Northrop Grumman — Weapons Integration

Advanced weapons systems, directed energy weapons, and fire control systems requiring precision-machined housings and structural components.

L3Harris Technologies — Weapons Electronics

Fire control electronics, targeting systems, and weapons-mounted sensors requiring precision-machined enclosures and mounting hardware.

Built for Defense Weapons Programs

Weapons system parts need a shop that understands mil-spec quality and defense documentation.

MIL-STD Documentation

Every weapons system order ships with dimensional inspection reports, material certs with heat lot traceability, and process records that align with MIL-STD and DFARS requirements.

DFARS-Compliant Materials

We source aluminum, steel, and titanium from DFARS-compliant domestic mills. Full mill certs and heat numbers on every order. No substitutions, no shortcuts.

CMM Inspection on Every Order

We verify every critical dimension before shipping. CMM reports go with every part so your receiving inspection team has the data they need for program acceptance.

Fast Prototype Turnaround

Program timelines do not wait. Prototype weapons system components in 5 to 7 days so your development schedule stays on track.
