A-square rifle question

[Big_Easy]

I recently purchased an A-square rifle and was looking for scope bases for it. The front mount also has two little holes in front of it (circled in red in the pic below). Im not sure if these are tiny screw holes, or if it was designed to have a scope base with 2 extra protrusions for additional secure contact with the barrel? I have other A-square rifles, and none of them have these two little holes there.
