Help Making ID

[blackhorse111]

This was in a lot of military gunsmith stuff i got a long while back. I am only guessing that it is some form of scope mount. Can anyone help me ID it mil or civilian, mount or no mount.

Thanks

That steel or Al? Doesn't look like a scope anything I've ever seen though.

Detachable scope mount for a com-block rifle? That was my initial thought.
