Help ID These Rings

[kmc0929]

Help ID these rings, I understand they are meant for a SIMRAD device - however not sure what manufacture or part number...

I need some of the small Torx screws replaced; trying to figure out the size.

The rings look like Leupold Mk4 rings, the sides of the rings have a slight radius and that's one way you can distinguish them from Badger Ordnance rings. Also the ring caps have an oval top as opposed to flat. The Simrad cap is a SPA B-621 made for Leupold rings.

The screws should be 8-40, I'd start there.
