I've got a 20" AR barrel off a Norinco CQ 311. A grinder was used on it to remove the front sight and the barrel is badly damaged because of it.

most of the damage is around the gas port...

Anyone think this barrel can be repaired/salvaged?

here are some pics:

I would just use a clamp on gas block. The cut across the gas port might cause a bit of leakage, but maybe not. A sealant could be used. Or, a lathe could be used to take a pass across the front sight base area, and a sleeve applied. Either way, a clamp on base would be the way to go.
 
Personally I view the barrel as scrap now, but you could rework it.
If you have the ability lathe the barrel and turn the gas port down and the area in front to a smaller diamter like .625 and get a Larue .625 gas block.

I am not sure why anyone would take a front sight gas block off that way - it is a guaranteed method to screw up the barrel like you have done.

That gouge in the barrel by the gas port is too large to fit a clamp on block over. Most gas ports on blocks are around .125" that would still leave a substantial amount of gap, and its close enough to the drilled area for the taper pins.

Personally I would toss the barrel, and put it down to a lesson learned never to let a retarded hamster work on a rifle...

I don't much about working with metal and such. what exactly does " a sleeve applied" mean

Just install a sleeve over the damaged area, with a hole lined up with the gas port. Turn the sleeve to 0.750" OD. There are a variety of moderately priced clamp on gas blocks in this size, some low profile, others with a rail to accpet a front sight. A clamp on gas block would avoid trying to retrofit a pinned on front sight base.
 
Use it for a dedicated .22 LR build ...
those old Norc CQ 311 barrels had the 1/12" twist, which is more desirable for a .22 LR conversion, and since you don't use any gas with a .22 LR conversion kit, you don't need to fix that horrible gouge in the gas port area.

PS: did that job come out of "professional gunsmith" in Calgary ....
there is a gun smiter there who "FITTED" a brand new Norc M14 into a brand new AKM stock, using that level of craftmanship.
