I have one of their stainless 18" premium barrels. I installed one in a friend’s rifle and was very impressed that I bought one for myself and put it in my LR308.
No idea about this one, different specs sort of. But it’s a 14.5 nitride. OOS though.
Check bkingsfirearms.com they have a ton of Ballistic Advantage barrels, I believe they have the 14.5 and their prices are really hard to beat. I use them A TON. But they are semi local (hour away across into Ohio). I order slot of my bulk small parts from them too.
