I am concerned about headspacing and timing. Are Remington's tolerances good enough to allow switching of bolts without headspacing/timing issues? I know that this may not be a perfect situation, but is it good enough from a function and safety standpoint?
No bolt change should go without checking the head space.
You can buy a go gauge and even a no go gauge and make sure for $30.00 each.
Then you can decide if it needs to go to a smith or not.
If you have to buy a used bolt, I would opt for a new one from PTG (But it would still have to
be head spaced).
