I watched a YouTube video of a guy asking of his gas tube was an issue or not. Everytime he would pull the bolt back and forth his gas tube would flex a little bit up and down (from hitting the gas key port).. Is it supposed to flex a little bit or should it not touch the gas key one bit? Seems kinda hard to get it perfect enough not to touch.. Mine does the same thing but I don't see how it would be a problem since it stills goes I
Into the hole just fine. |

If the top spine void of the barrel nut is set correctly, then is allows for some slop/movement of the tube through the upper receiver gas tube channel for the tube so semi self align with the key on mating.
But regarding index of the tube to carrier key, dry fit the carrier without bolt in the upper receiver to check. If needed and the gas tube needs to be index tweaked to correctly align with the key, then slightly bend the tube above the middle of the barrel. |
