You can buy a custom action for under $1,000 and one at the top of the range, with a high end trigger, mounted and timed for well under $2,000. No need to spend $3,000 or $10,000 for a custom rifle, though I would agree that IF the new owners in fact continue making 700s with the same quality, then with less than $1,200 (Stock work and new trigger all in) will get you a good shooting rifle. Just depends on what you think is good shooting. Yes under 1 MOA, but for 1,000 yard shooting you will need a lot better than that. My 700s all will hold .5 MOA after the actions were bedded, the triggers were replaced and the barrels were floated.
Unfortunately the barrel making machines were sent to Dakota Arms. Will have to see what they then do with the equipment as the Remington Custom Shop stopped using Remington Barrels two years ago and went with custom barrels from a few barrel makers. My last two Custom Shop 40Xs both have Krieger Barrels and Jewel triggers, direct from the shop.
