We use X-Caliber premium match grade barrels for our Custom Barrels. 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 a threaded muzzle with muzzle threads appropriate for the caliber (e.g. 5/8×24 for .30 cal, etc) unless you request otherwise.
We will match the most ideal rifling twist rate to your cartridge and barrel length selections. For example, a 300 BLK under 8 inches will be built with a 1:5 twist 5R rifled barrel, and a 300 BLK over 8 inches will be built with a 1:7 twist 5R rifled barrel. If you have a specific twist rate request from X-Caliber’s available options, please type that into the Notes field at the end of checkout.
>>> Because barrels are custom made just for you, cancellations are typically not possible. Likewise, change requests are typically not possible beyond 24-48 hours from when your order is placed. Lead time is approximately 6-10 weeks from order to shipment (some barrels ordered during COVID-19 times have taken closer to 10 weeks, and lead time varies depending on caliber, fluting, stainless vs. carbon fiber, etc., then Cerakote adds 1-2 weeks) <<<
