If you’re dealing with an obstruction in your firearm’s barrel, it’s important to use the proper tool for the job. Web searches from 2023-05-21 suggest that the best way to safely remove barrel obstructions is with a product called “Kroil”, a type of penetrating oil. If the patch proves to be stubborn and refuses to cooperate with the Kroil treatment, a “patch worm” may be necessary. In general, it is always advised to remove all live ammo from the weapon before beginning the disassembly process.

When using Kroil and a patch worm, start by removing the obstruction with the patch worm. Push gently with the patch worm through the barrel until the obstruction is pushed through. When the obstruction is removed, spray the remaining residue with Kroil to break up any remaining particles. Finally, use a brush to scrub the barrel and any other components that may have debris in them.

When cleaning an obstruction, it is important to always make sure that you wear appropriate safety gear, such as protective eyewear, gloves, and clothing. Additionally, make sure to read the instructions for your particular firearm carefully before attempting to remove the obstruction. Using the wrong tool can result in damage to the firearm or potential injury to yourself.

In summary, web searches from 2023-05-21 suggest that the best tool for removing barrel obstructions is a product called Kroil and a “patch worm”. The patch worm should be used to remove the obstruction while the Kroil will help break apart any remaining residue. Make sure to always use the appropriate safety gear when working with firearms and to read the instructions for your particular firearm carefully before attempting to remove an obstruction.
