Ballistic Advantage 6mm ARC Barrel 18" SPR Profile – AR-15 Platform

This 18-inch SPR-profile barrel from Ballistic Advantage is chambered in 6mm ARC, a cartridge designed for long-range accuracy and efficiency in the AR-15 platform. The 6mm ARC delivers flatter trajectories and superior ballistic performance compared to traditional .223/5.56 loads, making this barrel an excellent choice for precision shooting, hunting medium game, or extended-range target work. The SPR (Special Purpose Rifle) profile balances weight and rigidity for improved accuracy without excessive bulk.

Manufactured from 4150 Chrome Moly Vanadium steel with a QPQ Nitride finish, this barrel offers excellent corrosion resistance and barrel life. It features a mid-length gas system for reliable cycling with 6mm ARC loads and comes with a 5/8x24 threaded muzzle for compatibility with most muzzle devices and suppressors. Compatible with standard AR-15 upper receivers and bolt carrier groups designed for 6mm ARC (requires 6.5 Grendel/6mm ARC-specific bolt).
