Small Arms, Ordnance, and Ordnance Accessories Manufacturing

NAICS 332994 · Fabricated Metal Product Manufacturing · SBA size standard: 1,000 employees

Manufacturers of small arms, ordnance components and accessories produce firearms, ammunition, grenades, mines and related parts to exacting specifications. For a shop that machines barrels, assembles actions, loads ammunition and fabricates mounts and suppressors, the specialists convert customer orders and contracts into released work orders, raw material and component requirements, production schedules on shared equipment, quality and inspection checklists, serialized tracking and shipment paperwork. Blueprints, tolerances, ATF markings, lot traceability and test-fire records remain with the gunsmiths, machinists and quality personnel.

Workflows

Order and contract intake

Starts when: Receipt of customer purchase order, contract award or direct order request

  1. Capture order details including part numbers, quantities, specifications and delivery dates
  2. Verify against approved product list, licensing and customer eligibility
  3. Check material and capacity availability against current production schedule
  4. Draft acknowledgment and any required ATF or ITAR notices
  5. Create a released work order with linked drawings and routing

Watch for: Firearms and ordnance orders require verification of customer licensing status; Government contracts often carry specific marking, packaging and reporting clauses

Material and component requirements planning

Starts when: After work order release and weekly

  1. Explode bill of materials for each released order
  2. Subtract on-hand and on-order inventory including shelf-life items
  3. Generate purchase requisitions for bar stock, forgings, primers, powders and accessories
  4. Flag long-lead items and ordnance chemicals for advance ordering
  5. Update inventory projections and reorder points

Watch for: Explosive and propellant materials require special storage permits and handling; Raw materials must be traceable to mill certificates and heat numbers

Production scheduling and machine loading

Starts when: Weekly and after any priority order

  1. Load new work orders onto shared CNC, mill, lathe and assembly work centers
  2. Sequence jobs to minimize setups while meeting promised ship dates
  3. Balance barrel threading, receiver machining, ammunition loading and final assembly
  4. Identify capacity constraints and shift overtime or subcontract needs
  5. Publish daily shop floor schedule with operation due dates

Watch for: Certain operations require dedicated clean rooms or explosive-rated areas; Proof firing and function testing must be scheduled around range availability

Shop floor work dispatch and tracking

Starts when: Start of each shift and when operations complete

  1. Dispatch next operation packet with drawings, tooling list and inspection criteria
  2. Record start and completion times with operator and machine
  3. Capture in-process measurements and quality data
  4. Move completed parts to next work center or inspection
  5. Update serialized firearm log with current location and status

Watch for: Every serialized receiver must be tracked at every step; Nonconforming parts require documented disposition by quality personnel

Quality inspection and test documentation

Starts when: After each critical operation and at final assembly

  1. Generate checklist for dimensional, visual and functional inspections
  2. Record gauge readings, hardness tests and proof-fire results
  3. Link test data to specific serial numbers or lot numbers
  4. Flag any deviations for engineering or quality review
  5. Prepare final inspection packet for customer or government acceptance

Watch for: Firearms require headspace, firing pin protrusion and safety function checks; Ammunition lots require velocity, pressure and accuracy testing with retained samples

  2. Generate lot traceability reports for ammunition and ordnance
  3. Track and warn on expiring licenses, permits and registration dates
  4. Assemble export documentation packages when required
  5. Maintain bound books and digital records for inspection readiness

Watch for: Marking, serialization and record retention rules are set by ATF and must be followed exactly; Export of technical data or defense articles requires separate licensing

Shipping, transfer and fulfillment
