Hey everyone. First post. I purchased my m2 approximately a year ago. I absolutely love it. However I'm growing concerned. Every time I shoot, when I disassemble to clean it, the insides are filled with metal fragments. Tiny, almost like grains of sand. I know it sounds crazy, but I'm certain it's actually metal. Anyone experience this? It can't be from breaking in. There's just way too much metal debris. And even if so, I'm well beyond 1k rounds through it now.
