GunBlack is a family owned and operated metal finisher specializing in Black Oxide Finishing and Manganese Phosphate Coating.

Headquartered in Interlaken, New York, GunBlack is centrally located between Albany, Binghamton, Syracuse and Rochester. Serving the Northeast United States, we have satisfied customersĀ coast to coast.

We offer premium quality Black Oxide Finishing and Manganese Phosphate Coating (Parkerize) to Original Equipment Manufacturers and Full Service Gun Refinishing to gunsmiths and dealers around the United States. We provide the highest quality and service available in the metal finishing industry to the largest corporations and the average gun owner.


Founded in 1987 by the Kempf Family, Gunblack, Inc. immediately made its mark in the manufacturing world and gun industry. Serving some of the leading names in precision bearings and processing all of Ithaca Gun’s firearms gave us the experience needed to offer quality and service unmatched by our competitors. Starting with one production line offering both Black Oxide and Manganese Phosphate we quickly grew to three functioning lines providing both finishing processes in sizes up to 8 feet long and Black Oxide up to 16 feet long. We average 15,000 pounds each day in finished product with a turn around time better than one week for our OEM customers.
