What year is it? The wrench marks are on the mag housing collar. Wonder why some idiot would do that. The front mounting pin for the mag hsg is also gone.

I've use M60 bbl bags for my guns for 20+ years. They work fine for MP 40, Sten, M1A1Carbine, MAC 10/suppressor, Danish Madsen, folding stock AK and Thompsons w/o butt stock.
