Brand Recommendations for 8.5 300blk Barrel with 1:7 twist

Wanted to start a threat specifically for this configuration and some questions I had.

Currently finishing up on build a 300blk pistol with the barrel listed above primarily for home defense. I'm also pairing this with the SiCo ASR Bravo system with my lahar 30 can and was trying to go for a usable/nice flush look.

My goal initially was to go for a mid priced barrel around the $150 range from company's from rosco, ballistic advantage or faxon. Unfortunately they don't make a 8.5 inch barrel.

Anyways I'm might end up getting a Criterion but was wondering if this is overkill for 300blk at this length.

There is also kak and other random manufacturers that I've never heard of so wanted to hear some opinions of what people recommend for what's available out there. Been doing tons of research and not alot of info one some of those brands.
