The B14 is a CM barrel and black oxide finish , their more " production " rifle and the premier is a SS barrel and Cerakote finish, their more " custom shop " rifle and costs more money . The actions are the same it is just a little bit better components and more hand work . Both have the same accuracy guarantee. Either one is perfectly serviceable .

To me the stainless barrel and better finish are worth the extra change but everyone has different tastes / needs .

There is a renaissance at the moment in the precision rifle market going on now and there are a bunch of really good options in the market that used to be considered custom / semi custom at a price more in line with what used to be considered entry level / builder stuff .
