GC Precision Developments (GCPD) is an Australian owned, Canberra based design and manufacturing business. GCPD offers expertise in precision mechanical design and Computer Numerical Control (CNC) manufacturing techniques, and is one of a few Australian companies licensed to build and process strictly controlled firearms components and assemblies.

GCPD is a business trusted to manufacture controlled firearms, but also offers its design, prototyping and manufacturing services to all other industries that require precision mechanical solutions. GCPD has the full suite of capabilities that can take an innovative product from concept to production-ready reality.

GCPD’s core design and development staff have over three decades experience providing technical solutions to the defence, aerospace, scientific and marine petroleum sectors. Our pool of expertise includes:
  • Mechanical design and engineering
  • Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM)
  • Precision machining, production and integration
  • Equipment plant design
  • Technical support and maintenance
  • Industrial design
  • Systems engineering (test and evaluation)
  • Requirements engineering
  • Quality Control – documentation and test reports, qualification


GCPD offers a range of services that can either form part of your project, or complete in-house design, prototype and manufacture to your requirements.


GCPD utilises the Autodesk Inventor CAD system for mechanical design and optimisation, Finite Element Analysis (FEA) and drafting. GCPD can:
  • Take your concepts to a production ready design
  • Work with your drawings and models
  • Perform integration and reverse engineering work, or
  • Help you to develop an end to end solution


GCPD has extensive in house modern machining capabilities. Our facilities include:
  • Multiple CNC vertical machining centres and CNC lathe
  • Digitised manual milling machines and lathes
  • Electrical Discharge Machine (EDM)
  • Precision grinding
  • Heat treating facility
  • Abrasive blasting / shot peening equipment

Our CAM software allows us to complete all of our machine programming, either from our CAD models or those that you provide. We routinely work with differing grades of tool steel, aluminium and titanium alloys.

GCPD has a proven local supply chain that provides our off the shelf parts, and surface finishes such as MILSPEC hard anodising and Titanium Nitrite/PVD coatings.

GCPD can design and build one off prototype components and assemblies, and undertake low rate initial production, through to volume production runs.


We have access to two private firearm testing facilities, which enables GCPD to field test product ergonomics and accuracy under realistic and challenging circumstances.

GCPD also has the facilities to undertake firearm safety testing in alignment with Australian Customs legislation and Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) drop test requirements.


GCPD maintains the required licensing and storage facilities that enable us to work on an array of restricted items and projects:
  • Licensed to manufacture restricted items
  • Licenced firearms dealer, importer and exporter
  • Approved secure storage for controlled parts and complete firearms up to Category H and D firearms requirements
