Ok so I got my M40 back today and there's an invoice that lists 2 new parts and some fitting. It doesn't say anything about my barrell or chamber though and I sent it in specifically because it's bulging cases. If nothing is wrong with the barrell I wish they would tell me so I can feel safe shooting it. I tried to send an email to Allan Cornett but it bounced and continues to do so. Anybody know what's up?
