What Kind of Galil Scope Mount is This?

[zrunr]

Can anyone tell me if the mount in the attached picture is IMI or aftermarket and what type of scope it was designed for? It has a 30mm size ring. Did any of the pre-bans ever come from the factory with scope mounts or detachable bipods?

How tightly should a scope mount like this be attached to a receiver? How much of a mark would the screw leave behind on a receiver?

Going by memory because I sold mine, but that is the 30mm (Aimpoint) mount that used to be sold by Blackthorne.

Do they work as mounts? Can one use them to mount a 30mm optical scope?
