Got word back from KAK that the gas port on their 11" carbine barrel is .125". Should I get an adjustable gas block or will a regular one be fine? Just worried about being over-gassed. I am planning to use an H2 buffer since it seems like most people doing an x39 AR use that weight.

So much conflicting information :/

When he said it's a .125" port I asked him if an adjustable gas block is needed, he said he has never had to on his build with that barrel and an H2 buffer.

*sigh*

Not sure what to do now. Get a regular gas block because he says it works fine, or get the adjustable based in your experience. My gut is saying adjustable.

I would agree that a 11" carbine barrel with a .125" gas is way to large for that length barrel and cartridge.

The .088" gas port diameter is in the range that makes sense, so if your gas port  is at .125" you will almost
certainly be over gassed and will need a adjustable gas block.

Good luck.
