For repeatable, long-range accuracy with 6mm ARC, this 18 inch barrel in your AR-15 fits the bill.  This barrel from Ballistic Advantage’s Premium Black Series features 416R stainless steel construction, with a black nitride finish to resist corrosion.  The full rifle-length gas system is tuned to take full advantage of 6mm ARC’s mild recoil impulse, allowing you to stay on target, and keep your groups tight.

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.
