I removed the gas block and reinstalled it when changing the rail.  When I test fired it would not fire.  The round is chambering just fine and the lower receiver seems to be working properly.  I think it has something to do with the gas system but I'm not sure what it could be since it looked like I put everything back together the same way it was.  I really had to bang on the pins in the gas block to remove it but I read that that's normal.   Any suggestions?

Thank you for the advice and video.  I pulled the gas block off and reinstalled it again but still not operating properly.   A couple times I was able to fire a single shot but that's all.  So frustrating

General rule of trouble-shooting anything: start with the basics.

Is the gas piston in the "on" position? (button at 1:30 viewed from the front)  Try it at 12:00 (full open).  

If that isn't it, field strip everything on the upper and test fit each part individually into its place, if it has a spring try it without then with the spring.

Then go to larger assemblies, such as bolt carrier (stripped), barrel and upper assy, operating rod and piston (no spring)  can you push the carrier back by hand?

Go step by step in a logical manner.

If the barrel nut was torqued, or re-torqued, is it still aligned properly?

There is nothing in the gas system that will keep an AR from firing, except maybe a misaligned gas tube keeping the carrier from going into battery.

But since it is Adam Arms, I am assuming you are referring to a piston system.  It sounds like you re-installed something incorrectly, and it is preventing the BCG from seating all the way.  It may be something as subtle as not leaving the gap between the gas block and the barrel journal, if that is how it was built.  It doesn't take much rotation of the bolt for it to be out of battery.

It has the gap still.  The gas block was pinned from factory and pins went back in same place.

There is something else going on here.  the gas block would not prevent a cocked hammer from firing.  Did anything else happen?  Look at the BCG and fire control group, not the gas block.
