Muffer try 5thBatt or nzl1a1collector (on the FAL forum) if they can't help direct maybe know someone who can or who regular imports exports. I'll give my brother a call see if he knows anyone as he runs a Military vehicle club, may have a few contacts.

If you ever see anything in the UKicon similar or full rifle, sights etc don't hesitate to get in touch with me more than willing to help.
