Bolt Swap and Headspace

1007 Views 2 Replies 3 Participants Last post by  30Caliber
So I've got a spare TRW bolt (complete) that I would like to drop into one of my M1As.

Forgive the dopey nature of the question, but shouldn't I worry about headspace after doing so?

Thanks in advance for your help.

Yes, you should worry.
My first question is: Why change the bolt? Are you having trouble, or is it just for a spare?
Either way, you need to check (or have checked) your headspace before shooting a new barrel/bolt/receiver combination (in other words, if you change any of the 3, you need to check it). There are instructions posted elsewhere on this board, I just can't find them right quick (too much to do). Best of luck.
The chamber, the bolt and the receiver all have an impact on headspace.
