There are no Metal Injection Molded (MIM) parts in this BCG. All parts are machined parts. Black Nitride/QPQ: This is an extreme case hardening process which turns the steel black and hardens the surface of the steel and extends the life of the product. QPQ stands for Quench Polish Quench. This process is now commonly used in the industry. Our Black Nitride products are coated by H&M who own the trademark, "Black Nitride".
Proudly made in the USA.
