PRO TIP:: Larger the diameter, greater the Structural benefits. Smaller the diameter, lighter the barrel. Prioritize performance or weight.

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, removing 1-2 inches off the muzzle per vendor specification.  McGowen is shipped at selected length.  Weight is the estimated finish at a raw +1-2″ length and prior to gunsmithing.  To maximize barrel life, borescopes are highly recommended to guarantee a comprehensive and consistent bore cleaning.  Click here for borescopes.
