Hi all!
Got me some ufo handguards, went to fit them earlier but had trouble at the off. Removed the bolt but I couldnt get the flippin bar end off

I pulled, twisted, wiggled, jiggled all to no avail. It's like there's something holding it back and to top it off, I tried screwing the bolt back in but couldnt.
Sorry for the numnut question but I really could do with some advice. Fanks
