    All cycled fine.

    Just a data point for comparison as I have a near identical spec rifle.

    Talked to Troy at Bravo Co today. They got my rifle Friday and had it done today! The gas block was off center just enough and the tube was bent from that. I swear I adjusted that thing a couple times! His is why I let the pros look at it lol.

    I can not applaud BCM's customer service enough!

    I just looked back at my posts. I guess I deleted my response to IG instead of posting it earlier. I was thinking that since the barrel nut doesn't interfere with the tube like a normal barrel nut, the cocked gas block could cause the gas tube to be bent. I always like to check inside the receiver after a build and make sure the gas tube is centered inside the upper as well as slide the Bolt carrier without bolt in to make sure it glides in all the way smoothly without interference.

    Glad they got you fixed up! Good to see great customer service!! The gun industry is one of the last industries with actually great customer service! Way to go BCM!

    Interesting. I would have liked to have seen how far off it was. Was this caused by a defect in the barrel dimple location or something else?

    When you were checking the upper did you run a stripped carrier into the upper receiver and check to see if the key was binding against the tube?

    I forgot to ask honestly.

    I was close in my assessment. I wouldn't have guessed bent gas tube though.

    This right here is a key test that I've started doing since I took IG's class and he showed it to us. It's helped catch at least two that were binding significantly...one was a factory-assembled upper.

    PS, for what it's worth, my money was on the gas block as well
