PRO TIP:: Larger the diameter (DIA), greater the Structural benefits.  Each length boasts an optimal pattern and thereby surface-area-to-volume ratio.  Change the Length to reveal other Finish DIA options.  Change the Finish DIA to assess an optimal DIA to weight (auto calculated) ratio.

IMPORTANT::  Final diameters are estimated; not final.  All Structured Barrels® taper up or down to fit action.  Thus, the neck and action may have two different diameters.  Gunsmith cuts barrel to final length per vendor specification*.  McGowen is shipped at selected length.  Weight is estimated at finish length prior to gunsmithing.  To maximize barrel life, borescopes are highly recommended to guarantee a comprehensive and consistent bore cleaning.  Click here for borescopes.
