Ballistic Advantage 18" 6mm ARC SPR Profile Rifle AR-15 Barrel, Premium Black Series - BABL6MM002PQ

Ballistic Advantage 18″ 6mm ARC SPR Profile Rifle AR-15 Barrel, Premium Black Series

Optimized for precision, built for tactical reliability.

The Ballistic Advantage 18″ 6mm ARC SPR Barrel from the Premium Black Series delivers long-range precision and tactical reliability in a balanced, feature-rich package. Machined from 416R stainless steel and finished with a black QPQ corrosion-resistant coating, this barrel is designed for shooters looking to squeeze maximum performance from the 6mm ARC cartridge in the AR-15 platform.

Its Special Purpose Rifle (SPR) profile offers excellent rigidity for repeatable accuracy, while the rifle-length gas system helps tame recoil and promotes smoother cycling. The 1:7 twist rate is ideal for stabilizing heavier projectiles (80–108gr), making it a strong choice for precision shooters, hunters, and tactical marksmen alike.

Nickel boron-coated M4 feed ramps enhance reliability under stress—an essential feature for any 6mm ARC build where consistency matters most. Compatible with .750″ gas blocks, this barrel is engineered for premium performance without compromise.
