I have a 12.5” Criterion CORE 5.56/.223 Wylde barrel in good condition. It has previously been installed but never fired. In my research, I found these to be some of the most well made barrels out there.
It is carbine length ported, .625 gas journal and has a dimple for gas block alignment.
$200
I also have a YHM QD adapter for sale for $50.
