Manufacturer’s Description: This 2 oz. bottle of Black Magic™ is a high performance, premier cold bluing solution previously available only to gunsmiths. It produces a deep, penetrating action to restore worn or scratched gun metal to a like-new finish. Black Magic is the choice of major firearms manufacturers for touching up guns before they leave the factory. Black Magic is packaged with a child-resistant cap and includes easy to follow instructions.
We like it because sometimes there will be a scratch or minor repair done on your MAC and it doesn’t warrant a complete reparkerizing – it only needs a touch-up. For example you need to remove and reinstall one of the roll pins and during this process the receiver’s parkerizing becomes marred or scratched. The Black Magic™ Bluing Solution is the perfect fit.
