[ARCHIVED THREAD] - Upper Receiver Life?

Posted: 3/17/2009 8:36:47 PM EDT

Do upper receivers have a life span? I'm getting a new barrel and everyone has recommended that I get a new bolt. How long do upper receivers last?

BTW I have a 7 year old Bushmaster upper receiver that has abou 7K rounds thru it.

Thank you!

Does anyone know?

How many rounds has your upper receiver taken? 10K, 20K, 50K?
