Some of them are occasionally marked up under the handguard as well as farther back behind the Gas cylinder as this one was. I don't know why that happened but I have seen that before in both places. So if it looks and walks like a duck, you sometimes have to look hard to see it's a duck.
For those who don't know, Different has been unable to update his list on the forum for sometime now, according to what he told me. It's best therefore to send him the info in addition to posting here. He keeps a spreadsheet of his own and will always share info, except of course for the owners name with any who ask.
