new barrel, used bolt question

[rif4trbo]

Hi, I tried searching and couldn't find the answer, Im getting a new barrel from a reputable co. because of a warranty issue the gun has 3k rounds thru it with a BCM bcg. My question is can i use the original bolt or should I replace the bolt with a new one and is it ok to put a new bolt in a used carrier thanks
