Gunsmithing Can the front flush cups on an Accuracy International AT rifle be removed?

[archer6]

The flush cups (for slings) on the rear had a screw that was easy to remove. The front ones however did not have screws. I tried to lookup to see if anyone has done this, I didn't want to force anything. Does anyone know how the front ones are attached?

I have two ATs and mine where easy to remove. They where held on with a allen key screw.
