"Even went to the US ARMY armour course and scored the highest score in the class."
So help me out brother, why would a gas tube break off at the gas block on this gun. I can not see any signs that someone hit it, so what gives. I don't think the gun could get so hot that it would burn off. I have not taken it apart yet (the boss whats me to get parts first) so I can give you more that what I can see with the hand guard on. I will put up some photos when I get it apart.
Second Q is any suggestions on putting the gas block back on. Getting it off looks OK and I have found videos showing that. I have not found any videos showing how to put it back on. Do I need to worry about the front sight alignment, do I need new pins or use the old ones, do I need to mark the block so I can line it back up correctly. Any tips would help. Thanks
Any by the way, I have went to the Colt armour school and they even told use we did not need to line up the gas rings.
