For what its worth I owned an FN SPR a couple years ago. It was a well built rifle, fit and finish were definitely above the price point that I paid (approx. $1500). From the factory it had a McMillan A4 stock with adjustable Kydex cheekpiece, Near 20moa scope base, and factory DBM (which is actually pretty good) and the trigger was nice and crisp, factory barrel was 24" which is plenty for a .308 win.
The downside, and the reason I eventually traded the rifle away was that it was close to13 lbs, you can get a fluted barrel version but it doesn't shed that much weight. When I mounted my Leupy Mark 4 6.5-20 the rifle was approaching 15 lbs with ammo. I carried it around in an eberlestock backpack but unless I was shooting stationary for long periods the rifle was just too heavy for my applications.
In my opinion the SPR would not be a good choice for a backcountry rifle or one used for backpack hunting situations. Just my two cents!
