Manufactured to our exacting specifications and used in all of our rifles, JP Supermatch™ barrels are turned from 416R stainless steel, lead lapped, air-gauged and cryogenically treated for cold bore shot predictability, minimum thermal drift, outstanding accuracy and extended barrel life. All barrels also include a JP EnhancedBolt™ individually head-spaced to the barrel for flawless fit and function.

This barrel will accept our JPTD750S Thermal Dissipator but only with some modification for length. The price in the drop-down at right reflects the JPTD and necessary labor.
