NBlue.jpgIf you are a gun enthusiast who enjoys light gunsmithing projects, you will be interested to know that you can nitre blue gun metal without using salts. To use nitre salts, you have to heat the solution, slowly dip the parts in and hope that they come out looking even. It is definitely a process that requires multiple practice runs before attempting to nitre any actual gun parts. However, there is a much simpler solution if you want to nitre blue your gun metal. Simply do it with heat and without tedious salts.

How Can I Nitre Blue Gun Metal Without Nitre Salts?

The process is easier and quicker than using salts. If you heat the metal evenly for a long enough time period, it oxidizes and changes colors. Do not expect a vibrant royal blue. This process will bring a nice subtle but darker blue color, which creates an attractive and sleek look on a gun. As you heat the metal, you will see the color change. Use a screw to practice first so you can see how easy this is.


What You Will Need

  • Metal screw
  • Propane torch
  • Vice grips
  • Striker
  • Personal protective gear

Steps To Nitre Blue Gun Metal Without Nitre Salts

If you are new to gunsmithing or using a propane torch, it is a good idea to wear protective gear. Wear gloves and goggles. When working with a torch, make sure you do not have baggy clothing or sleeves.

1. Grip The Screw

Place the threaded part of the screw in the vice grips. Tighten it enough that the screw is held in snugly but the threads will not be damaged. When using handheld vice grips, make sure the handles are in good condition to avoid burns.

2. Heat The Screw

Use the striker to ignite the propane torch. Hold it so the tip of the torch's flame touches the screw's head. Move the torch around in circles on the screw's head slowly.

3. Watch For Color Changes

As the screw's temperature changes with prolonged flame exposure, it will start to change color. It will start with a light but dull color change. Heat it evenly around the head for a continuous color. When the head of the screw turns purple, be sure to watch it closely. The next color change will be blue.

That is all it takes to nitre blue gun metal. Perhaps you have an old pistol that looks rough and needs a makeover, or you just like blue gun metal. This is a great project for any gunsmithing enthusiast. Check out SDI's YouTube Channel for additional gunsmithing tips.

Wars within the War

img-roland-220x130.pngDuring this time of war, in addition to the regular attacks on our troops by enemy forces, there have also been other types of attacks. These "green on blue" attacks are "friendly" forces killing our troops. In 2011, there were 35 instances. In 2012 so far, there have been 51. These things get quite a bit of media coverage due to the loss of life as a direct result.

Something that concerns me just as much, if not more than "green on blue" attacks, is the threat that wears the same uniform as my wife. Sexual harassment and assault are a big problem within the military. Men and women are victimized by their comrades. As a Army civilian employee, I have to attend the Sexual Harassment/Assault Response and Prevention program, along with the Soldiers. It is saddening to hear the stories of those that have been attacked by people they trusted with their lives.
