AR 556 Rattling when firing

Recently noticed when firing the AR 556, a loud rattling noise is coming from the stock or buffer, havent figured it out exactly yet. My question is should I replace the stock or the buffer/tube/spring? not a huge deal just annoying

Its the buffer and spring doing its job. Its simply a quirk of the AR-15 platform. They all do it.

Normal sound on an AR. Careful, it also makes a huge bang when you pull the trigger. (Kidding...kidding)

If you're meaning the "sproing" that happens with each shot, that's your "magazine is not empty" indicator.

Once the magazine is stripped of it's last shot, and that last shot is fired, the sproing disappears. This is due to the bolt being held open by the bolt catch, which means there is no sproing, which means that your magazine is now empty.
