The Ballistic Advantage 8.6 Blackout 16-inch AR10 Barrel (brand part no. BABL86B003PQ) is a heavy-contour, carbine-length barrel built for shooters running the increasingly popular 8.6 Blackout cartridge on a .308-pattern AR platform. Part of Ballistic Advantage’s Premium Black Series, it’s machined from 416R stainless steel and finished with a QPQ corrosion-resistant coating, then proof-fired and magnetic-particle inspected before it ever leaves the shop. Whether you’re building a suppressed hunting rifle or a hard-hitting AR10 for the range, this barrel gives you a verified, drop-in-ready foundation. It’s a straightforward upgrade for any AR10 owner looking to add 8.6 Blackout capability to an existing build.

Key Specifications

• Barrel length measures 16 inches, a versatile length that balances maneuverability with the velocity 8.6 Blackout needs to perform.
• Chambered in 8.6 Blackout, a purpose-built cartridge for suppressed, subsonic-capable AR10-pattern rifles.
• Features an HBAR heavy contour that adds mass forward of the receiver for better heat management during sustained fire.
• Runs a carbine-length gas system for reliable cycling with a standard AR10 gas block and tube setup.
• Machined from 416R stainless steel, a premium barrel steel prized for accuracy and corrosion resistance.
• Finished with QPQ nitride coating that resists corrosion and wear without adding the cost of chrome lining.
• Every barrel is proof-fired before shipping to confirm it safely handles pressures beyond normal service loads.
• Barrels are MPI-tested (magnetic particle inspected) to catch subsurface flaws that visual inspection would miss.
• Sized to the AR10/.308 bolt pattern, fitting compatible .308 AR uppers and barrel extensions.
