Try Sinclair/Brownell's. They have a tool for it that uses the firm cotton rolls that your dentist uses to hold your cheek away from your teeth. This will get most of the real grime out of the lug recesses. You can cut the length of a roll to fit the diameter of any rifle.Hi can anyone tell me if there is a way to clean the bolt lug recess if you do not have the probeer tools? Non of my locals gun shops seem to have lug recess and chamber cleaning tools. I wanted to order j dewey tools online but they charge 121$ for the cheapest shipping option to where I live. That is 5 times the price of the kit I wanted to buy and I don't want to pay that much for shipping. So if anyone can give me any tips on how to diy it or use existing cleaning rods I'd appreciate it.
