I was going through some old totes and found these in shit shape. Box was water damaged in my storage unit. Im going to clean them up if for no other reason than to save the clips. But, is this just surface crap on the rounds that can be cleaned, or is this a no go for shooting? Im split 50/50, concerned enough to ask. This is all modern production PPU. No older than 5 years old. Was in storage for 2 years.
