The clearest civilian match is gunsmithing and precision firearms repair. Manufacturers, large retailers with service shops, and independent gunsmiths hire technicians who can headspace, fit, and repair to spec. BLS groups detailed precision-shop wages with related production roles, and Tool and Die Makers, a close skill cousin, post a median of $63,180 per year (BLS OEWS, May 2024). Precision Instrument and Equipment Repairers (O*NET 49-9069.00) is the cleanest catch-all O*NET code for armorers moving into civilian precision repair.
Maintenance and machinery roles take the rest of your skill set. Industrial Machinery Mechanics (O*NET 49-9041.00) earn a median of $63,510 (BLS OEWS, May 2024) and the field is growing faster than average as plants fight to keep equipment running. Machinery Maintenance Mechanics and general Maintenance and Repair Workers (O*NET 49-9071.00, median $48,620) hire constantly across manufacturing, utilities, and logistics, and your habit of diagnosing from a technical manual is a direct fit.
If you liked the inspection and gaging side of armorer work, Quality Control Inspectors (O*NET 51-9061.00, median $47,460) and Machinists (O*NET 51-4041.00, median $56,150) are strong landing spots, especially in defense manufacturing where your background is an asset rather than something to explain. Be honest with yourself about geography: gunsmithing and defense manufacturing cluster in specific regions, so the highest-paying precision roles may mean a move. The maintenance and quality roles are everywhere.
Defense primes and federal arsenals value this background directly. For a sense of how weapons-repair experience reads across branches, the Marine 2111 Small Arms Repairer and Navy GM Gunner's Mate pages map the same civilian targets. For the trades side of the house, our guide to military-to-trade careers walks through how mechanical MOSs convert.
