Rear mount for the fr 8 sniper rifle ?

Hi
Here is a new picture of a FR 8 sniper rifle with some type of sight or rear mount for the FR 8 sniper rifle
Sorry it is the only picture I have.
Best Regards
Bob

There was a thread about FR-8 'Snipers' on gunboards long, long ago. I think the Spanish did scope some, as they appeared mixed in with the imports, but I'd be really cautious. If you don't know what it should look like, assume it is likely bubba to be on the safe side.

Since there seems to be no front scope mount on this rifle I doubt this is a FR8 with scope bases. This appears to be an adjustable rear sight.
