Heavy SPR Profile 6mm ARC Barrel for AR-15

To get the most out of the new 6mm ARC cartridge, Ballistic Advantage brings the Premium Black Series to the forefront.  Constructed from 416R Stainless Steel for accuracy, and finished with black nitride for durability, this barrel helps get the most out of the 6mm Advanced Rifle Cartridge.  The SPR profile keeps the barrel rigid from chamber to muzzle, ensuring repeatable accuracy over long range.

This barrel also features a Nickel Boron coated barrel extension, ensuring reliable feeding from your magazine.  The extension mates up perfectly with any upper with M4 feed ramps.  Be sure to check out a compatible 6mm ARC/6.5 Grendel bolt carrier group, as well as a magazine to complete your build.
