But I can say that Compass Lake Engineering, who are about as reputable as it gets in the field, & who install both Bartlein & Kreiger barrels, told me that they do not nitride any barrels because that prevents them from ever fully "breaking-in".
FWIW

I've had a few nitrided barrels and don't particularly love them. One of my buddies was having Lilja barrels nitrided when he shot 6.5-284 in NRA Long Range and said it was a waste of time and money. When I ordered this gun I asked about getting a non-nitrided barrel because my .223 Wylde from him is plain stainless. He didn't have any non-nitrided so I ran with it. If and when I wear this one out the next one will just be regular stainless and when I put together an upper in 6.5mm for this one it won't be nitrided either.
