Snip** Kind of reminds me of when you drink too much hootch and you get that ringing sound in your head before you throw up all over your girlfriend, and then she gets mad at you and won't even take care of your cat for like 3 bloody weeks.
I do no see a weld anywhere on this flash hidder.
This rifle has a 2013 sn from what I see, is there any chance they didn't do it in this year?

Does your flashider have 2 discoloured blobs right behind the bayonet lug, or 2 holes?
If 2 holes, you're in the clear, if discoloured blobs, then those are the welds.
I just did this today on one of my 2012 Norinco shortys. I searched the internet this weekend, and found a gunsmith in Edmonton who was calling this video the 'Bubba'd method.
