@Foxyboy43 I believe that you are correct in your thinking in your example, certainly in my experience with my FAC. My understanding is that the FAC provides granted permission to acquire, and use the items written onto it according to the conditions set. The way this works on my FAC (West Yorkshire) is that the firearms (including moderators) are conditioned for use on MOD approved ranges and over land for which I have permission to shoot. On my cert the rifles and moderators were granted by calibre as I requested them in pairs. In practice I use my 6.5 mod on my .223 because it fits and works well enough.
