The best way I found to mount a scope to a Hakim is to find one of those side mounts for the SKS and mount it to the receiver. I did not do this to mine but helped a friend do his. The mount was ordered from tapco. The base was a mounted to the side and the mount attached to this, similar to the side mount now found on AKs. No, a mauser mount will not work. Tried several.
There was a mount that (once again) attached to the side of the receiver of a German mauser for attaching a small scope that would probably work but that mount if original would be worth twice what you paid for the Hakim.
