Instructions:
Select a Max DIA followed by Caliber and Length.  If a preferred setup is not shown, change Max DIA and repeat.  Feature letter codes are for internal, order processing only.  Form is logic-based, automatically updating options and price per end-user selections.

IMPORTANT: Larger the diameter (DIA), greater the Structural benefits.  Final diameters and weight are estimated; not final, and excludes exterior finishes and gunsmithing.  All Structured Barrels® taper up or down to fit action.  Thus, the neck and action may be two different diameters.  Gunsmith cuts barrel to final length per vendor specification*.  McGowen is shipped at selected length.  To maximize barrel life, borescopes are highly recommended to guarantee a comprehensive and consistent bore cleaning.  Click here for borescopes.  Customer assumes complete responsibility for discovered blank defects from a barrel manufacturer that includes but not limited to rifling, bore, and material, and indemnifies TACOM HQ of all liabilities.
