Trybe gas tube alignment problem - TRYBE Defense AR-15 Gas Tube, Pistol/Carbine/Rifle/Mid Length

The gas tube looks fine, it is the correct diameter and length. I tried installing the gas tube, the Trybe gas tube and the Trybe gas block pin holes don't line up. I don't know if it's the gas tube or the gas block or both that's the problem. The gas port holes line up correctly. I've installed many gas tubes before, the roll pin drives in easily, but this time it went in halfway and stopped. Upon examining the gas block closely I found the pin holes were misaligned. I can't use it in this condition.
