adjunk on my 500 mossburg.

how hard is it to put ghost ring sights on the plain 18.5" barrel? It has the brass ball on the barrel now. I have installed the recoil reducing adj butt stock and fine the sight pictures now off.

XS sights are probably some of the best sights available on the market.

You may want to call them and ask about installation.
