Core Responsibilities

Primary Functions

Operate a variety of manual and CNC machine tools, including lathes, milling machines, and grinders, to produce firearm components such as receivers, barrels, slides, and bolts from raw stock.
Interpret complex engineering blueprints, technical drawings, and CAD models to ensure all fabricated parts meet precise dimensional tolerances and specifications.
Perform intricate hand-fitting, filing, stoning, and lapping of metal components to achieve a perfect, seamless fit and exceptionally smooth action in the final assembly.
Assemble a wide range of firearms, including pistols, rifles, and shotguns, from individual components, ensuring proper installation, function, and timing of all parts.
Execute precision TIG and other welding techniques to join, repair, or modify firearm parts, ensuring maximum structural integrity and a cosmetically clean finish.
Apply a diverse range of metal finishing processes, including bead blasting, polishing, chemical bluing, Parkerizing, and Cerakote application, to provide corrosion resistance and achieve specific aesthetic outcomes.
Conduct thorough diagnostic assessments on malfunctioning firearms to accurately identify the root cause of mechanical issues, wear, or breakage and develop an effective repair plan.
Perform function checks and live-fire testing of newly built, customized, or repaired firearms in a designated test facility to verify safety, reliability, and accuracy.
Machine and thread barrels for the precise installation of muzzles, suppressors, and other muzzle devices, ensuring proper concentricity and alignment.
Fabricate one-off custom parts and accessories from scratch, using creativity and problem-solving skills to meet unique customer requirements or to prototype new designs.
Install, bed, and pillar rifle stocks to create a stable, stress-free platform that significantly enhances the firearm's potential for accuracy.
Calibrate and zero sights, scopes, and advanced optical systems, ensuring they are correctly mounted and aligned with the bore for first-round accuracy.
Maintain and repair shop machinery and gunsmithing tools, performing routine preventative maintenance to ensure they operate safely and accurately.
Carefully document all work performed on build sheets, work orders, and digital logs, maintaining meticulous records for quality control and traceability.
Adhere strictly to all company safety protocols and federal/state/local regulations regarding the manufacturing, handling, and storage of firearms and ammunition.
Gauge and inspect barrels and chambers using precision measurement tools to ensure they conform to SAAMI or other required specifications.
Perform advanced modifications such as checkering, serrating, and stippling on wood and metal surfaces to improve grip and enhance the firearm's ergonomics and appearance.
Select appropriate materials, such as specific steel alloys or polymers, based on the application's requirements for strength, durability, and weight.
Collaborate directly with design engineers and R&D teams to provide valuable feedback on manufacturability and potential improvements for new product designs.
Troubleshoot and resolve complex assembly or component-fitting challenges on the production line, acting as a subject matter expert for other technicians.
