    I have a couple questions. where do i take a barrel measurement from? How much of that is functional rifling after the chamber? for example my stock mod 70 barrel is stated at 24 inches. How much of the 24 is functional rifling? thx

    Barrel length typically includes the chamber and the shank that is threaded into the receiver. If you only measure the exposed portion the barrel your measurement is about an inch short.

    The barrel length is measured from the bolt face with the bolt closed to the crown of the barrel.

    Roughly, the stated barrel length minus the COL.
