Abstract
A low observable, brass ammunition cartridge casing with an exterior surface having a colored coating which renders the cartridge casing low observable. The colored coating may be deposited onto the exterior surface by various processes, such as electroplating, chemical deposition, and spray painting. The colored coating may be selected from a variety of different colors such as, black, olive green, silver, brown, tan, gray, and white. The colors are typically obtained using conventional pigments and colorants, such as metal oxides. The brass casing exterior surface may be roughened to reduce the gloss or sheen of the casing on the colored coating. The invention includes ammunition cartridges containing a low observable brass casing described above.
