Once I pulled the bolt and slid the carrier in the upper I felt it bump against the gas tube. I tried the carrier in another rifle and it had no resistance and was smooth. I loosened the hand guard nut and I could notice a change in the alignment of the gas tube. The carrier will now slide in with no issues. I was also able to pull the gas tube out of the upper. Thanks for the answer. I'll wait till morning on trying to get it all back together again.
