Size, Length, and Geometries
Larger the diameter, greater the Structural benefits.  Blanks are not guaranteed to finish at or under the Max Diameter limit.  Click here to compare the weight of a Structured Barrel to a bull and taper at varying diameters.  All Structured Barrels taper up or down to fit action.  Thus, the neck and action may be different diameters.  Gunsmiths chamber, thread, and cut the barrel to final length per vendor specification*.  TACOM HQ processes all blanks at raw length.  McGowen is shipped at selected length.
