Do our prefits shoot as good as our full rifle builds?
They certainly have the ability to! All prefits are chambered in the exact same way the barrels for full builds are. However, a rifle is a complete functioning system with many parts. If your action is giving up ignition energy or the bedding is not stress free for example, then the potential performance, of the barrel can be masked by other problems. SCR specializes in and prefers to do the full build that way no stone is left unturned.
