I am a fan of the Remington 700, as I posted it is my go to rifle for most of my hunting. However, I am not blind to its faults. First, I would not buy a new one, all mine are from the last century, all built in the 80s except one from the 90s.
I swap in the older bolt locking safeties on mine, I prefer the safety to lock the bolt shut. I also screw and epoxy the trigger connector to the trigger, eliminating the dangerous floating connector which has caused lots of problems for Remington. I have not had an issue with extractor, and am not sure that anything needs done to it. I guess if I have an issue that would change my mind. The failure I describe above is the first I have had in the field. I decided to add the second ejector because I believe that even though a bolt is maintained properly, a piece of grit or brass shaving can make it stick. I would much rather have a claw extractor and a standing blade ejector, but not sure it is worth the disadvantages in the 700 (possibility of blown out extractors, different ejection angles, weakened bolt). I saw a Remington 700 at a gun shop in Anchorage that had been retrofitted with a Mauser style claw extractor, but I do not believe anybody does that conversion any longer.
