Front Bead protrudes into the Barrel

Hi,
My 500 is about two years old --- one of the tactical looking models.
I noticed the I could see the bottom of the bead on the inside of the barrel.
I assume it is the threads that I'm seeing. I can barely catch my fingernail on it. So it only protrudes into the barrel a few thousandths. I've only fired 1 slug through it and a half dozen buckshot loads.
Is this a problem?
Will it affect slug accuracy?
If so, what is the fix? (remove the bead and reinstall with Loctite and only flush with the inside of the barrel surface?)
thanks
Charlie
 
Slugs and shotcups have to be catching on it, whether or not it will affect accuracy I can't say. A shotgun is not a precision instrument so I may not affect it in any noticeable way but it's not a good thing.

I would not take the loc-tite route. If it was me I would grind it down so it will fit snug but not protrude into the barrel. You just need to be careful not to ruin the threads else you won't be able to get it back into the barrel.

I might be just as easy to buy a bead with a shorter post.
 
I agree with WM on the loc-tite, but I would use the Blue Loc-Tite.
