If you have an AR-10, other non bolt action .30 cal, or .308 caliber rifle then 5/8x24 is the typical tpi required. We offer this threading service with turn around time of a week to ten days, depending on arrival of your barrel. This price is for us to receive the barrel only, additional charges for removal of uppers and/or parts is additional. Standard return shipping with this length of barrel is $29.99 but can be more depending on specifics. *For Bolt action rifles see our bolt action barrel threading. Please call with any questions. Thanks
