Step One: Remove the Old Barrel
Before installing a new barrel, you will need to remove the old one. Start by securing the firearm in a barrel vise. Use a barrel wrench to loosen the barrel from the action.
A firearm action wrench may be necessary to hold the action steady as you loosen the barrel. Once the barrel is loose, gently remove it from the action.
Step Two: Cut the New Barrel to Length
The new barrel should be cut to the desired length before it is installed. Depending on available tools, this can be done with a saw or lathe. Measure the length of the old barrel and use that as a guide to cut the new barrel to the same length.
Step Three: Install the New Barrel
Once the new barrel is cut to the correct length, it is time to install it. Begin by placing the barrel in the barrel vise and securing it firmly. Next, insert the barrel into the action and use a barrel wrench to tighten it. Make sure the barrel is seated correctly and tightened to the appropriate torque.
Step Four: Pin the Barrel in Place
To ensure that the barrel stays securely in place, it is necessary to pin it to the action. Use a pin punch and hammer to drive the barrel pin through the barrel and into the action. Ensure the pin is seated correctly and does not protrude from either side.
Step Five: Weld the Barrel in Place
The final step is to weld the barrel to provide additional security. Use a TIG or MIG welder to weld the barrel to the action carefully. Be sure to wear a welding helmet and protective gear to avoid injury. Use a continuous bead of weld around the barrel to ensure a strong connection.
Pin and welding a barrel to a firearm requires careful attention to detail and a good understanding of gunsmithing techniques. If you are not comfortable with these tasks, it is best to seek the help of a qualified gunsmith. Following these steps, you can install a new firearm barrel.
