So I disassembled my xm-18 and lubed it up. When I reassembled it I centered the blade and its a little off (don't care) it's super smooth but the pivot is pretty much free floating... I can spin it with my hands like I'm swinging the knife back and forth. its not unscrewing it moves as 1 peice. Just seeing if this was normal, there's no blade play or anything it just wasn't like this when I got it so I don't know any better
