JP RIFLES | JP Supermatch™Barrel JPSM223-18L8R7
JP Supermatch™ barrels are manufactured to our highly exacting specifications for superior performance and optimal fit with our components. These barrels are turned from the finest 416R stainless steel and then lead-lapped, button rifled using state-of-the-art equipment and air-gauged to ensure minimal bore diameter run out for peak accuracy. We also make a point of cryogenically treating all of our rifle-caliber Supermatch™ barrels for cold bore shot predictability, minimum thermal drift, outstanding accuracy and extended barrel life.
All Supermatch™ barrels (excepting 9mm) come with an individually head-spaced JP EnhancedBolt™ assembly and can be purchased in either Black Teflon® or one of several stainless finish levels. 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.
