Full 20 Inch Designated Marksman Barrel for 6mm ARC
The Ballistic Advantage Premium Black series starts with a solid foundation: 416 Stainless Steel to maximize accuracy, with black nitride finish to resist corrosion. The 20 inch length of this barrel imparts incredible velocity to an already accurate, efficient round, ensuring that you’ll reach your target at long range. The heavy DMR profile also gives you repeatable accuracy for tight, sub-MOA groups with match ammo.
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.
