Yeah, that's crap. USPS to AK is cheap

Personally, I wouldn’t mess with ordering for McGowen/CarbonSix for a while. From a YouTube video they put out this year, they’re going through a lot of business changes, are going to sunset McGowen, and are moving most/all of their customer service to AI as I recall.

That seals the deal, looks like Shaw/bca/xcaliber are the 3 barrels of choice for us.

Great job! That's a great option to have.

To add a suggestion: With their Easter sale going on right now, anyone wanting this option, I'd suggest ordering it right now, directly. That's a good deal. I think by the time the barrels would be shipped to me, and then additional shipping to the next person, it wouldn't be all that much cheaper, and more hassle for everyone.

Ugh, I've been wanting an AI barrel...

Any idea what kind of velocity loss one can expect when firing standard 223 ammo in an AI chamber?

From the examples I've read, not a lot. Seems to be less than 50 fps from what I recall.

I have one data point:

Howa mini 223 factory 1:8 barrel cut to 16”

- 77tmk 26.5gr lever LC brass 26.5gr lever 2.435” oal, 2807fps

- same, but 26.7gr lever 2849fps


Howa mini Shaw 1:7 223ai barrel 16.5”

- LC brass, 26.5gr lever 2.35” oal, 2815fps



I’m pretty sure you can count on max load for 223 shooting similarly, if a slight drop in velocity, while forming 223ai brass.
