I redid this reply. You got me thinking. Did I really see fn? I just took a cursory look at the time and there was some gunk kinda smeared over it. I saw Fabri something and do to my ignorance presumed FN. I had to look again. Took mount off and lightly cleaned some of the gunk off with 0000 steel wool. Nothing else would work. It's a Fabrica de Armas oviedo markings. I am not disappointed in the least. I would rather know then be wrong. Thanks for your expert info.
That makes sense. Everything was screaming "93 Spanish Mauser" except it being an FN; I'm not aware that FN made any pre-98 receivers, but hey, ya never know. I was actually hoping to see something unique; maybe FN did a weird limited production run of replacement receivers for the Turks or something. Heh.
Thank you for checking.
