How to Blue a Rifle Barrel Using Cold Blue | The Model 67 Project | MidwayUSA
This GunTec video from MidwayUSA demonstrates a cold bluing process for a rifle barrel using Art's Belgium Blue. Hosted by Larry Potterfield, the method involves heating the barrel in hot water, plugging the chamber and muzzle with wooden dowels, applying the bluing solution with cotton swabs and deliberate strokes, and repeating the heating and steel wool scrubbing process until the desired finish is achieved. The video highlights the aesthetic appeal of a well-blued barrel.
