Seiler Instrument’s Manufacturing Division manufactures optical instruments and components commercially and for the military, primarily the United States Government. Seiler is the original equipment manufacturer for optical fire control used on all United States howitzer and mortar systems. We are responsible for the machining, assembly, and testing of all optical fire control system components.
Seiler also specializes in the inspection, repair, overhaul, and refurbishment of artillery fire control on all existing United States howitzer systems as well as many howitzer systems used by our Allies. Refurbished fire control can extend the life of your weapon at a fraction of the cost of replacement.
