JP RIFLES | JP Supermatch™ Barrel JPSM223-18L8R7-HP
JP Supermatch™ barrels are manufactured to highly exacting specifications for superior performance and optimal fit with JP 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. JP also makes a point of cryogenically treating all of JP's 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. More about JP Supermatch™ Barrels
