I bought a 20" Wylde 1:8 nitrided barrel to re-barrel my shot-out A2 Service Rifle because I'm building a flat-top 'optics' service rifle and will not be shooting the A2 seriously in competition, and the Bear Creek barrel cost half what a "good" barrel cost.
At 100 yards, prone, on the reduced prone slow fire target, it shoots little knots. I am shocked at how well it performs and wonder why it was so inexpensive. It may shoot poorly at 600 but I will not be shooting it at 600 in competition, so who knows?
So I can't really answer your question, but the barrel I bought from them exceeded the 'quality' I thought I was paying for.
