It's a tough proposition buying one of these from pictures online. Unless it is a well known NFA dealer with a money back guarantee it could be a big gamble buying one without a hands on viewing. Most of the time the gun is several states away and all you have are pictures & trust.
So, my question, how can you tell if a M60 is a re-weld? I have read that even if the manufacturer box on a Form 3/4 reads Maremont for instance that it can still be a re-weld! I have seen pictures of the trunnions that what appears to be pins welded into the trunnion and I have seen the holes where these pins were grinded off smooth. Which one is original?
