FAC/SGC holders will be much more likely to record details of their non FAC rifles (I would assume. I do), so wanted to separate them from non FAC/SGC air gunners if you see what I mean?
A FAC air rifle would have to have it's serial number recorded, but non FAC rifles don't. I'm just curious to know how many non FAC rifles have their serial number recorded/saved/written down by the owner. I think that makes sense
Original question really refers to serial numbers specifically - pics an added benefit
