Out of spec tubes, or a sloppy fit can result in gas leakage. But, if we couple gas leakage at the block, with an out of spec gas port, and some other issue like bad gas rings then we have a recipe for disaster.
The next area of concern for the gas tube, is the where the gas tube meets with the bolt carrier key. A correctly made gas tube will be flanged at the top where it meets the key and provides a seal. If this area wears down, then gas will escape. The cause of excessive wear is a misalignment of the gas tube with the carrier key.
This is also directly related to proper installation to include gas block alignment. Top- Worn gas tube. Bottom new gas tube. This subject is not without controversy. Stakings have changed over the years. Original carriers which were hard chromed had a different staking which was done with a center punch at the top of the carrier.
This later changed to 2 staking points on each screw. Additionally as referenced in an old print, Permatex 3D was applied in an area below the carrier key. I have not seen this done in several years and I cannot be certain it is still a requirement. The torque value of the carrier key screws is very minimal 58 in. Equally as important are the correct screws. There are those who refuse to believe that these screws can and will loosen over time with use.
I have seen it so many times, I have lost count. Sadly, many cannot do it correctly. If the carrier key is not seated correctly, the screws are not torqued and staked properly they can and will loosen. This results in massive gas leakage as well as damage to the gas tube. And last but not least, we have the bolt gas rings. The gas rings are essentially the cheapest part of the gas system, and probably the most overlooked.
