I have a Grendel I'm building for long distance shooting. I got the chromed "Hard-Use" bolt for it, and I thought to get chromed carrier to match. Is it worth it to get the Young Manufacturing "National Match" bolt carrier group, or would any chromed carrier do as well?

In other words, does a bolt carrier have anything to do with accuracy at all? I intend to shoot to 1000 yards, so every bit helps.
