PROBLEM FIXED! :D
Who installed the gas block and FSB? Can't they make the repairs? Or you just do not want their booger hooks on it again, fearing they will make it worse?
I'd touch base with Robb Jensen at VA Arms and/or Grant Timberlake at G&R Tactical. Both of them have done awesome work for me.
Contact ADCO and see if they can help you get your canted FSB straightened out
If you are in Cal, you may need to have "an assault weapon certified" smith work on it. Evans gun works(?) in Anaheim can work on registered assault weapons. If it is an off list lower gun, I think anyone can work on it.
I know of two smiths in SoCal, if you need their names let me know.
I wouldn't take it to Joe Gunsmith down the street for such a job, either for installing the thing and especially not fixing it if it's screwed up. Too many bubbas with a drill press but no jig. If the FSB was installed off-vertical on the barrel...that's bad. Not sure how you'd fix that, but you should check with ADCO about your options. I've had ADCO install a few FSB's for me and they've done an excellent job. If I were you, I'd be pricing new barrels too.

Perhaps someone qualified can properly align it and pin it through the top side?

Is it pinned or clamped on with screws? If I is clamped on just loosen the screws and turn it to line it up.
Its clamped on....can't you just loosen it and adjust.

The only gg&g gas block I saw was a clamp on. Just loosen the screws and line it up. The smith may not of properly torqued the screws.
Since you have other carbines, first determine if its pinned vs set screwed. Pinned is hard to adjust a small amount, but not a big deal to correct, as you can convert from (badly) pinned to set screw with a new gas block plus hide the pin holes in the process. Just have the smith place a dimple in barrel where set screw makes contact, use locktite, should be gtg. As others have said, if block was not pinned, then fix is super easy, as long as gas port hole is top dead center of barrel.

If it's clamped on as suggested here - check to see if the barrel was dimpled for the setscrews. If it wasn't, I'd personally send it to ADCO for a dimple job. I did that with my only setscrew gas block, it's nice being able to remove it if needed and reinstall it in the exact same position.
OP, is this your gas block?

If yes, should be an easy fix.
From the photo it appears that the OP has a pinned on version like this,

and not this.

GG&G doesn't have his version listed on their website Storefront but it is shown in their pdf. catalog. They recommend sending the barrel to them for installation. Hmmm.
I think i found a guy that can do this properly.
I seem to recall this can be fixed by pulling the pins, jigging it straight and then drilling for oversized pins.
Good luck!
Is it tilted to the left? Sometimes that happens when the barrel nut is tightened because there is a little bit of slop in between the upper receiver notch and the indexing pin on the barrel and the barrel can spin just a little bit when tightened. I've seen this a lot on rifles with front sight bases and I usually straighten them by holding the fsb with something while torquing the barrel nut down. Make sense?
