I bought an M&P 10 recently and when I was doing the initial cleaning in preparation for going to the range I realized the barrel was pretty dirty. It has definitely been fired. Does anyone know the procedure at S&W with these rifles? I assume it was test fired at the factory, but the barrel was pretty dirty. Overall though, there is no evidence of wear on the rifle. I have an M&P15 sport and a 9mm shield and I didn't notice the barrels really dirty at all. I bought the gun from grabagun.com, which I've never done before but it was the best deal on this relatively expensive rifle. Thanks for your input in advance.
