Ballistic Advantage 6mm ARC 20" DMR Barrel – AR-15 Platform

This 20-inch DMR-profile barrel is purpose-built for the 6mm ARC cartridge, delivering the extended sight radius and velocity needed to exploit the round's long-range ballistic efficiency. The 6mm ARC offers superior ballistic coefficients and retained energy compared to traditional .223/5.56 loads, and this barrel length maximizes those advantages for precision shooting at distance. Ideal for designated marksman setups, long-range target work, or hunters who need flat trajectories past 500 yards.

Manufactured from 4150 Chrome Moly Vanadium steel with a mid-length gas system for reliable cycling and reduced recoil impulse. The barrel features a black nitride finish for corrosion resistance and extended barrel life. Fits standard AR-15 upper receivers with a barrel extension and M4 feed ramps. Requires 6mm ARC bolt and compatible magazines; this is not a drop-in replacement for .223/5.56 uppers without those changes.
