I just joined this forum and am looking for some advice. I have an older model 41 and want to remove the muzzle brake. I removed the screw but still can't seem to budge it as far as removing it Does anyone have any ideas that I can try? I soaked the space between the muzzle brake and the barrel but maybe I will have to wait for this to work. Could this piece possibly be threaded on? Any help would be greatly appreciated. Thanks guys.
