Carbon Six offers two main styles of muzzle threadings as well as custom threading options. 5/8″ x 24 TPI -&- 1/2″ x 28 TPI
During your barrel order, you can to select which option you would like from the pull down menu. Either option is available for $60. Have an unusual threading? We are able to do that as well. Just select custom threading and we are glad to thread your muzzle any way you’d like for only $80.
We highly recommend you add a thread protector to any threaded muzzle. Choose either a basic knurled version ($20), which is pictured below or a smooth blended protector ($70) that is made of the same high quality stainless steel as the barrel core, but machined to a seamless finish.
