Hi Guys, I was adjusting one of my MP40's and noticed these under it. Any idea on what they could be? They seem very hard, and very hard to remove. One looks to have coralline in it?

Yeah, Thats what I just came up with online after you told me what they were. Thank you again guys for all your help, I can now sleep tonight![]()
