  • Markers will be serviced based on availability of parts in the order they are received. Usual expected turnaround for repairs/service is about 3-5 business days from the date your marker arrives at Field One Paintball. If there is an issue with the marker that will take an extended period of time to resolve, a Field One Paintball Technician will contact you with further information.
  • Service Center Customers will be notified when their marker repair is complete. Payment will be collected at that time and the marker will be shipped to the return address using GROUND shipping. 
  • The minimum cost for F1 maintenance/repair service is $55.00 plus shipping.  Repairs/issues covered under warranty will be done at no charge- customer is responsible for shipping cost.  Please see the Field One Warranty page for details.

    This service includes:

    -Marker Inspection/diagnostic

    -Software Update (if available)- Flash Main Board 

    -Replacement of engine o-rings and seals (if applicable/needed)

    -Rebuild of marker regulator (if applicable/needed)

    -Cleaning/inspecting eyes and detents

    -Set Chronograph speed to 270-280 FPS (This will need to be checked and adjusted by the customer before playing with the marker). Markers are generally tested at 10.5BPS (NXL Ramp) before they leave the F1 Service Center.

    Any repair or replacement parts that are required to complete service will be an extra charge. Customers will be notified if replacement parts cost is excessive. Excessively dirty or damaged markers will incur an additional labor cost.  The owner of the repaired marker is encouraged to test and chronograph the marker upon receipt from the F1 Service Center to ensure that the issues have been resolved/ maintenance performed and that the marker is functioning well.
