I have thought about using Teflon tape but thought it might be a bad idea. Guess I was wrong! I’m new to MLers, but my breech plug has never been difficult to remove. I have been using XF7 Weapons Lubricant, SPARINGLY, on my BP since day one. My longest shooting session has only been 50 or so rounds, but at the end, removing it was a breeze, and I tighten it down pretty good. I may cut that out though since I’ve learned it’s not necessary.
I use the XF7 on my M14 (a gun that requires GREASE, not oil!) and, I have to say, it’s amazing stuff.
