Well, lets hold off for a quick minute.
Millett approved the refund. I will probably buy another one unless someone can suggest a 20+ magnification scope for 500-600 bucks.
And, I called CMMG to trouble shoot. IMMEDIATELY, they asked me to send it in. They said it might be one of the older models that over-gasses. They have since improved it. they wanted to see my gun to rule it out. Sending them the gun today on their dime. Fingers are crossed that they find the issue.
