We get a lot of questions regarding the CarbonSix barrel profiles.  Some early barrels pictured on the site showed a different taper, and that has caused a bit of confusion.  Our barrels all feature a “straight” taper, 2.5″ default shank length, and 1″ default muzzle length.  The diameter varies by contour & threading.

Muzzle Diameters
Featherweight – .750″
Sendero – .830″
Magnum – .900″
Bull – 1.00″
