You mean a linear brake or a krinkov type? Do you have any pictures.First off is it possible to remove it without screwing up the barrel? If it is possible is it legal to replace it with a front venting brake? Also, would this effect the ARs accuracy and fit?
Anything that you touch in a barrel can potentially change the point of impact. Adding or removing or moving can change the harmonics of the barrel.How would it change the point of impact?
The only thing that cleans really well is an ultrasonic machine (sorry Mr. newyork brake) and a copper brush, metal pic right there where the carbon accumulation is building up. Some finishes are better than others but eventually will be like a solid rock and the smaller the ports the worseWhy not just soak the tip of the barrel in hoppes and blow it out with gun cleaner for hard to clean brakes?
Probably not but might give you that nice smell of grandma's cooking. try also some garlic olive oil. lol.I wonder what would happen if you sprayed the brake with Pam before every shooting...might clean easier
I have not tried anything like this but I believe it will not work because the part will not be freely exposed to the vibration and frequency setup. the rifle will muffle all that. I am sure there is a method but at the same time there is no need to reinvent the black powder in the year 2012.Think it work if I built a bracket to hold my AR vertical, muzzle down, then insert just the brake area into an open ultrasonic bath for cleaning?
