Pentrate

Pentrate Metal Processing and California Electroplating are federal and California-licensed providers of finishing services for firearm components. They handle both high-volume manufacturer runs and individual gunsmith projects.

• •Black oxide finishing (traditional "bluing") is their specialty—available in high-gloss for custom builds or matte for restoration work. Since black oxide adds no appreciable thickness, it maintains dimensional tolerances on precision parts.

They also apply: - Phosphate coatings (equivalent to Parkerizing) - Nickel plating - Chrome plating (hexavalent or trivalent processes) - Satin or bright finishes on cast and stamped components

Their team handles all regulatory paperwork according to federal and California firearms regulations. No surprises, no delays—just clean parts on schedule.
