Black Collar Arms barrels deliver match grade precision and look dang good while doing it. At the same time, they’re durable and all-but-impervious to the elements thanks to their stainless steel construction and hard-as-nails salt bath nitride finish. Caliber designation and small Black Collar Arms “collar” logo are engraved around the shoulder.
These are “pre-fit” barrels and use a barrel nut to make adjusting headspace and locking the barrel to the action simple and fast. Each barrel includes a Black Collar Arms Barrel Nut with 1.25-inch wrench flats. See the Barrel Nuts page for more information.
