There should not be J locks on new production Remingtons. And, it still no big deal to replace it with a different shroud. And, 700P or 700VS or 700VSF are all the same action. Just a different finish. Personally I do not like the palm swell of the PSS stock. Close out VS's can be still for 550 to 600 NIB. A factory barrel in 308 should give you decent accuracy to about 4K rounds or so. Hey after all it is mass produced factory barrel! And, working up a load for the 308 is basically a no brainer! Varget, Lapua or Winny Brass, CCI BR2 Primers topped off with 168 or 175 SMK! Done deal!
That aside one has to remember that the FN SPR comes with barrel that will hold less then MOA well towards 10K of rounds down the tube. It comes with 20 MOA scope mount. A multitude of McMillan stocks and barrel lengths can be had!
There is afterall the Tactikewl factor of a FN SPR. Functionally, Savage with McMillan stock is nearly half the price! And, you get a adjustable trigger! Then you can spend the other half of the money on glass! And, still be way a head of the game!
Supposedly the new 700P can be had with an externally adjustable trigger this year. A this option is a long the lines of XR100 or 40XB Tactical with it being user adjustable without taking down the gun!
Afterall what do you want it for? Do you want to punch paper and perhaps a club level shoot? Or are you a slotted member of a LE agency having to supply his/her own weapon!
