H&R sight mount.

[Mustang]

I posted this on the smallbore forum also.

I'm trying to mount a Viani scope mount on one of my M12's and am having difficulty identifying the fasteners that are holding the base on.




The fasteners have a round hole withwhat looks like a start shape in the bottom.

What kind of tool do I need to remove these fasteners?

Thanks

Yeah, my H&R 5200 and my other M12 are both hex...this one turned out to be torx...was able to remove them with a T10 torx bit.
