Remington has been using CNC equipment since at least 1980, and probably prior. CNC whatever means little if things are not processed correctly. Not really knocking Remington, but last I saw they were still using Monarch VMC's to machine the receiver. Nothing wrong with the idea if everything is done right from the start. Having seen the fixture, I can tell you right away it's a poor design done cheaply. Why they never incorporated a drill guide into the design is a complete mystery. Still you can drill and tap holes extremely accurate if you do it right. Others have said they are single pointing the threads now, but I've yet to see a single action without a tap parting line in the threads. Must only be sold on the east coast and west coast! Besides gunsmiths need the money just like everybody else does.
The only thing that has ever seriously concerned me about a Remington 700 is their safety. It works like a teenager with a part time job. The trigger can be replaced, but no matter what I cannot trust their safety.
Still if you just want a shooter right out of the box that works every time. Then buy a Howa.
