[ARCHIVED THREAD] - Changing an upper receiver

Posted: 9/8/2011 4:09:14 PM EDT

I sent in an upper for barrel threading. It currently is an A2. If I wanted to change the receiver to a RRA A4 you have listed on your website, can that be done considering you don't have my bolt carrier assy/bolt for checking headspace?

Yes we can. Headspace on an AR is not user adjustable, so unless your bolt is worn beyond recognition, then it will be fine.
