How would I proceed with seeing if mine is one of the one's that CAN be? Do I send the upper to you? I was told that the fake vortex was "blind pinned, welded, and sanded". SAW led me to believe they had added a real smith vortex (picture on their site) but added a completely different one. I am very interested in changing it and by what I have read, you are the company to send it to. Please let me know.
