Here are the best 4 ways to remove rocksett off firearm muzzle brake threads to help with removal.
Dissolve In Hot Water
Rocksett is heat resistant, but it’s water soluble. So dip it in water and let it sit for 5 – 48 hrs as needed based on your particular scenario. Generally speaking, 3 – 5 hrs (overnight) is enough and you may try around this range and then increase the boiling time when you need to.
After that the rocksett residue should fall off the thread, then use a brass brush to clean up the threads.
