That sucks, they are barely visible....i thought mine was special....guess not....welded it is.
Yes, it is easy to be fooled. I thought my 2010 standard version was not welded, but when I tried to remove the flash hider, it became obvious that it was.
Still, this is a minor issue. M14 Doctor field fix for this is to have a seated buddy firmly hold the stripped barrel/action assembly across his lap. Loosen the gas lock and swing the gas cylinder to one side. Back the castle nut off as far as it will go, and hold the rifle so the bayonet lug is up. Use a decent sized hammer and a large brass or mild steel drift on the base of the flash hider or bayonet lug and give it a sharp blow. Didn't budge? Quit hitting like a girl and try again!
When it begins to move, continue backing off the castle nut and striking until the flash hider falls off.
Sometimes the flash hider will crack - perfect excuse to replace it with something decent.
If it comes off intact as usual, just file or dremel out any burrs and smooth off any rough spots on the barrel. Many of the stock flash hiders are poorly machined with the splines or sight base crooked, so check it out closely. Replace it if it worries you, but in reality all but the most wonky ones will still allow you to zero your rifle.
Once taught this simple method, I have removed more than a few flash hiders in this fashion. I think there is very little chance of bending a barrel this way also, as it is pretty well cushioned by your buddies thighs. If he whines about bruises, you are hanging out with the wrong crowd
