If the bolt doesn't match then it came from another rifle.
Bolts are not interchangable so it would be advisable to check that the locking lugs fit properly against the locking lugs on the rifle body.
If they don't you could have problems, its not impossible to resolve it but it will take some work.
Just post again if you need guidance as how to mate (properly) a bolt to a rifle.
Thanks! I will be taking it to my gunsmith to have him check it. I'm looking forward to shooting it in a few weeks.
