So, I ran 6 or 7 mags through the .223 Tavor with a suppressor, and then started cleaning it.
Talk about a PITA.
There is soot throughout the internals, and no easy way to get to it.
I think I'm going to have to completely strip it down to have a chance at getting it clean again.
May need to find a large sonic tub and dunk the whole thing.
Don't think I'll be running a suppressor on it again.
