We use X-Caliber premium match grade barrels for our Pistol Build Kits. These made-to-order barrels are among the highest quality and most accurate barrels available in the country. All barrels ordered through Black Collar Arms include a barrel nut for easy, custom headspacing and muzzle threads appropriate for the caliber (e.g. 5/8×24 for .30 cal, etc).
