Well for one accustock adds to the price, myself I would rather buy cheaper 10 version with no accustock 10 FP, then add stock from B&C or HS or Choate, but that's just me. 10 FP and 10 Precision Carbineis build on the same action, the differences here are the stock and the internal mag verses detachable on Precision Carbine. But Precision Carbine only weights 7 LB from one point its light and should be good for carrying it in the field, from another point light weight doesn't add to the stability of carbine. Anyway I already congratulate you on your purchase, now take it to the range and whatever everybody saying not to, but do a proper break in. Scope is up to you, Leupold, Nikon, Millet, Vortex, Bushnell or Burris would be fine, magnification I think you won't shoot it pass 300 yards and for that you should be fine with 16X max, just search who is running better sale on optics and pick the one you like... I used to shoot my 308 with 9x Nikon scope on 500 yards, there were no problem hitting 6" plate...
