Well, that's the 20in model with the fluted or unfluted barrel. FN makes a very nice production gun.
The original SPR, before there were others.....had a 24in barrel and an HS Precision stock. The gun is great, people like them very much, not just for the gun but for the fact that they were being sold on the net for like $900. The gun was a great deal overall.
Since then, FN has come out with some new models and all use different McMillan stocks (no more HS stocks).......with these changes, a fairly large price increase followed.
While the FN SPR series guns are good out of the box, they aren't the greatest deal when compared to the original one.
If I recall, the A1a retails for over $2,100. Not sure what the street value is, but I'll bet it isn't much lower.
For that kind of coin, you could get a custom rifle.
That's what I would recommend, you'll get a better gun for the same or a little more money (GA Precision, Nor-Cal, etc). Just will take some time to get though.
Since you're not a PD, why go with such an expensive production bolt gun....that's really who these FNs are intended for.
Scope wise, I like Leupold.....but there are others (Nightforce, etc).
You have the luxury of going custom. Go for it, assuming these prices aren't scaring you
