With production on the [Criterion] CORE barrels being rather slow, and it taking 4 and 6 months between availability on various lengths, we started to look at other options which we could more readily provide, and more consistently offer fully assembled uppers with.

That’s where our THICC barrel started. It should be available in another week or two now.

Chrome lined, 5.56mm chamber, .750” gas journal that takes a FSB if you want, phosphate coated, 4150CMV, 1:7 twist, .078” gas port, 13.95” length which takes a ton of muzzle device options to make it up to 16.1”.

...

Our THICC test barrel (nitrided 416R instead of chrome lined 4150) grouped right about 1” with 69gr Federal Gold Medal Match, suppressed (at 100y). The thicker contour also minimizes zero shift with an added suppressor, we saw .5” of zero shift at 100y with a Sandman S mounted (on the heavier side for suppressors on 13.9” barrels).

We’ll post the results of our production barrels once they come in and we test them, but they’re gonna be shooters, and they’re gonna be available.
