Frequently asked questions
about Mustad Belgium.

Mustad Belgium produces machined components and sub-assemblies for defence programmes and industrial sectors, operating around 60 production machines with production up to 24/7, high-precision tolerances, consistent quality and full lot-by-lot traceability.

Mustad serves two markets: defence, with over 1,000 different components produced for OEMs and prime contractors in Europe, the United States and the United Kingdom, and industries, covering several sectors from medical to rail and precision equipment.

Mustad Belgium was founded in 1948 in Eupen, Belgium, as part of the family-owned Mustad International group founded in 1832 (Norway). The company has built long-term partnerships with defence OEMs and industrial customers across Europe, the United States and the United Kingdom.

Both. Mustad built its reputation on leading defence programmes, producing over 1,000 part numbers. That same standard — traceability, consistent quality, round-the-clock production capacity — now serves several industrial sectors.

Continuity. Mustad Belgium is a family-owned company founded in 1948 and active in the same trade ever since. Customers running multi-year programmes never have to change partners mid-programme, and production runs up to 24/7 on 60 in-house CNC machines, backed by a sustained investment policy that keeps us competitive.

Three areas: machining capabilities (Swiss-type and multi-spindle bar turning, CNC turning, 4- and 5-axis milling, with engineering, assembly and finishing around them), a quality system certified ISO 9001:2015 since 1996 with an EN 9100:2018 certification targeted for 2027, and a working method built on a two-working-day feasibility review and co-engineering.

Swiss-type turning from Ø4 to 32 mm, multi-spindle lathes, CNC turning up to Ø75 × 900 mm from bar with two or three turrets and up to Ø350 mm in chuck work, and 4- and 5-axis milling up to 600 × 600 × 600 mm in robot-loaded cells for series production, centreless grinding, deep-hole drilling and laser engraving, complemented by finishing, mechanical assembly and 3D metrology. Production is automated with bar feeders and robot loading and can run up to 24/7.

Assembly, press fitting, grinding, tribofinishing and laser engraving are performed in-house. For heat and surface treatments, Mustad works with qualified partners — or with yours — and helps select the right partner for each requirement, with every operation documented lot by lot.

Highly automated: bar feeders on the turning side, robot loading, multi pallets and pallet towers on the milling side, so machines keep producing around the clock. That automation is what lets a workshop of this size run up to 24/7 and hold series in the millions of parts.

Mustad Belgium works with the following materials: free-cutting, alloy and case-hardening steels, stainless steel, aluminium, brass (including lead-free), copper alloys and plastics.

Yes. The European Union is progressively phasing out lead-containing materials. Mustad has proactively developed and optimised its manufacturing processes — machining strategies, tooling and process control — to integrate lead-free brass into production while maintaining the same quality standards.

Mustad Belgium has been certified ISO 9001:2015 (BQA_QMS_C_1993029) since 1996 — three decades of audited quality management. The company is also engaged in an EN 9100:2018 certification targeted for 2027 for aerospace-grade quality requirements.

Mustad Belgium machines components to high-precision tolerances and holds them in series production. For each programme, inspection methods are matched to the customer's requirements and correlated with the customer's own measurements, and critical dimensions are verified with documented inspection reports for each delivery.

Traceability is guaranteed at every step: materials, treatments and inspection results are tracked lot by lot, from raw material to delivered components. Each defence delivery ships with its quality documentation, meeting programme-specific requirements. Quality records are retained for 10 years.

Mustad Belgium provides a first technical feasibility assessment within two working days of receiving your CAD files or technical documentation. The assessment covers lead times, materials and critical tolerances, and can be handled under NDA on request.

Send your CAD files or technical drawings. Within two working days, Mustad's technical team returns a first feasibility assessment covering lead times, materials and critical tolerances. Confidentiality is guaranteed, and an NDA is available on request.

Yes. Through reverse engineering, Mustad measures the existing part and rebuilds a complete, production-ready definition, which is validated before series production. And when only an idea exists, co-design takes it from concept to a finished, producible component.

From multi-year framework agreements to call-off orders on demand, our organisation adapts to yours. Every programme keeps a single point of contact from first article to series production, and business is conducted in English, German, French and Dutch.

Yes. Mustad can take on a component family as a second source, reducing a manufacturer's dependence on a single supplier and adding a supply option based in Belgium, inside the European Union. Parts are machined to the customer's drawing with lot-by-lot traceability.

Yes. Mustad can add complementary capacity when volumes rise, during a load peak or after a supplier failure, with 60 production machines able to run up to 24/7 in Eupen. Each ramp-up is organised with the customer — need definition, feasibility, qualification where the programme requires it, then production planning.

No. Mustad manufactures components and mechanical sub-assemblies that its customers integrate into their own systems, plus its own mechanical products such as the Universal Sight Mount. Its role in the value chain covers manufacturing, industrialisation and design — not complete systems.

Mustad Belgium is registered as a supplier with the NATO Support and Procurement Agency (NSPA) and is identified in the NATO Codification System under NCAGE code BTS84, which can be verified publicly. The company works directly with defence prime contractors in Europe, the United Kingdom and the United States.

Mustad produces over 1,000 different defence components across three categories: small arms components for military and sport platforms, ammunition components up to Ø120 mm, and parts for weapons systems — from vehicle platforms to sighting and observation systems. Sub-assembly is handled in-house.

Yes. Mustad Belgium manages heat and surface treatments through its network of qualified partners, and carries out finishing and assembly operations in-house. You receive finished, ready-to-integrate parts from a single supplier, which keeps your supply chain as simple as possible.

Yes. Around 30% of production is exported. Mustad Belgium regularly supplies defence OEMs in the European Union, the United Kingdom and the United States, in compliance with applicable defence export regulations. Export licences are handled in-house, and each delivery is shipped with suitable packaging and its quality documentation.

Bolts, breech blocks, bushes, cam pins, ejectors, extractors, firing pins, flash hiders, hammers, housings, lower and upper receivers, rifles and pistol slides, hunting gun receivers, machine gun top covers, muzzle brakes, triggers, sighting supports and washers — proven across the world's most widely fielded weapon platforms, from single components to assembled sub-assemblies.

Yes. Alongside firearms parts, Mustad machines weapon accessories and PICATINNY mounting systems for sighting and optronic equipment; every accessory is produced with lot-by-lot traceability.

A secured building with controlled access, monitored day and night by a security company, where sensitive components are stored and handled accordingly. Technical data are circulated on a restricted basis, a documented and regularly tested disaster recovery plan (DRP) covers production as well as IT systems, and enquiries are handled under NDA on request.

Mustad machines ammunition components from small calibre up to Ø120 mm.

Mustad machines ammunition components from a few thousand to several million parts.

Grinding, tribofinishing and laser engraving are performed in-house. For heat and surface treatments, Mustad works with qualified partners — or with yours. The team has long experience with treatments and helps select the right partner for each requirement, with treatment records documented lot by lot.

Every lot is tracked from raw material to delivery: material certificates, treatment records and inspection results are documented lot by lot. Deliveries comply with defence programme specifications and ship with their quality documentation.

Mustad machines components for military vehicle platforms and sensor systems, vision and fire control equipment, drones and missile programmes — plus accessories for the optronics that equip them — as a build-to-print partner for defence OEMs and prime contractors across Europe, the US and the UK.

Both. Most weapons system components go straight from customer drawing to production. When a definition still has room to improve, Mustad's engineers review it first — relaxing non-critical tolerances, suggesting alternative alloys, flagging manufacturability risks — so the programme reaches series production without surprises. In some cases, we have also proposed a completely new design.

Yes. Assembly, press fitting and laser engraving are performed in-house, so weapons system components arrive as ready-to-use sub-assemblies rather than loose parts. One partner, one quality system, one point of contact.

Weapons system parts are the largest in Mustad's defence range. CNC turning covers components up to Ø75 × 900 mm, and 4- and 5-axis milling handles parts up to 600×600×600 mm — housings, brackets and mounts, from first articles to series production.

The Mustad Universal Sight Mount is a sighting support designed and produced in-house by Mustad Belgium for .50 cal M2 HB, M2 QCB and M3 machine guns. It is machined as a monobloc from aerospace-grade aluminium and carries three PICATINNY rails compliant with STANAG 4694.

It fits M2 HB, M2-QCB and M3 machine guns chambered in .50 NATO. Its geometry preserves the original iron sights on M2 HB and M2 QCB, so backup aiming stays available without removing the mount.

Yes. The mount is secured by three cam-lock levers — two vertical levers locking to the top plate of the receiver, one horizontal lever for lateral stability. No tools are required for installation or removal, making it field-operable.

Yes. Alongside build-to-print production for defence OEMs, Mustad designs proprietary products. The Universal Sight Mount is the published example: specified, engineered, machined and assembled in Eupen, with surface treatments carried out by our qualified partners.

Mustad serves several industrial sectors: medical, entertainment, rail and industrial vehicles, connectivity and precision equipment. All are produced in the same Eupen workshop, with the discipline built on defence programmes.

Because defence-grade discipline transfers. Industrial customers get the same tight tolerances, lot-by-lot traceability, two-working-day feasibility assessments and round-the-clock production capacity that NATO defence programmes require — applied to their own components.

From pilot runs to series of several million parts per year.
