I've had very good experiences with Criterion barrels.

If I was building a new urban combat AR carbine today, this is the barrel I'd order:

For a pistol, I'd look at their 11.5" carbine gas:

I'm also very impressed with the FN barrels I have. For Cold Hammer Forged AR barrels, they would be at the top of my list.

As for BCM, they earned their reputation. I needed to upgrade some BGC, so I have a new BCM complete BGC and an additional complete Bolt on the way.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
