A I have a gorgeous 1100 with an LPA ghost ring sights on it. I love it! So, I'm thinking about sending barrel to Vang Comp for their barrel treatment. I notice their ghost ring sights look just like the LPA set. What is the purpose of the rail attached to the Vang Comp sight? What else could I possibly attach to that rail? I only put a rail on my 1100 for the rear sight.
My thought is to send the whole gun in, do the barrel, Vang sights, and ceracoat the whole gun. OR drill/tap, add my own rail, mount up the sights and ceracoat myself.
I just don't get the stubby little rail.

Thoughts?
It DOES occur to me that the sight is removable, then you get the rail to add a red-dot or something??
