Custom Barrel

From: $425.00

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 8-12 weeks from order to shipment (some barrels ordered since COVID stuff began have taken longer, and lead time varies depending on caliber, fluting, stainless vs. carbon fiber, etc., and Cerakote adds 1-2 weeks) <<<
