Maybe. I'm more inclined to think that they have scratched that itch and are moving on...but like the optic. I once just had to have a CETME .308. I don't know why...but I needed it. I bought one and put a red dot on it. I kept it for about a year or two...mostly gathering dust in the safe. Sold it, kept the optic.Who else sees an ad like that and the thought process goes right away to "the gun must shoot for shyt." which is why he's selling it without the scope he had on it at the range.
I also sometimes see the old scope not included around here as well line. Meaning the gun sucks but I want to keep the scope.
But yeah, the gun might be a jammomatic, too.
