What do we think about Bison Armory barrels?

I dont have any experience with them. What brought you to Bison ?
Just looking for a 22" heavy, fluted, non threaded and they are about the only ones that offer that for under $400 without going full custom and spending a ton. I have read good things about their 6.8 barrels but I'm looking for sub-sub moa not just sub moa lol. Not sure they will fit into that requirement.
