Fucking gunbroker. I like that site, but you gotta be very careful. Guys mis-label their hardware, whether out of ignorance, laziness, or maliciousness, all the damn time.
I don't believe that "logo" is the company who manufactured the BCG. It was probably just an option to add, or was added, for that BCG.
If you bought a factory "Noveske," I am assuming you spent at least 2k. If I spent 2k, I'd be contacting that seller to fix this deal. The fact that you already had the rifle transferred to you sucks, but unless they specified that the BCG was not factory, they should be willing to help you fix the issue...even if they helped pay half for a new one or whatever.
Then again, if it doesn't bother you, rock on. I just get irritated with the constant mis-representations.
