Personally I believe "assembled using a Rem 700 action" or what ever is closer to reality. There are damned few that actually "build" anything. Assemble a bunch of parts, yes, build , no.
It seems that the AR crowd is the worst for this type of terminology. Assembling an AR is childs play, actually building 1 from raw materials is a little more complicated.
But then again I am old school.
