I recently acquired a NIB pre lock SA Mil-Spec. Everything looks pretty good but I do have a question about the barrel link. On the outside of the link near the pin there is a small groove that runs across it. Is this a normal machine mark or is it an issue ? I'm hoping it isn't a crack but it really doesn't look like one. Does yours have this or have you seen one like I describe ? I had it cleaned & back together before thinking about taking a pic.
Thanks.
Thanks.
