Our spiral fluted 300 Blackout Rifle Barrel provides the same rigidity, strength and lightweight balance as our straight-fluted Heavy Barrel in a more aesthetic and modern twist (literally). The spiral fluting of this Heavy Barrel reduces its overall weight, provides better heat dissipation, and offers a more solid feel with fewer harmonics compared to any M4-profiled or contoured barrel. It's the best of both worlds.

Rifled and Fluted to Extreme Tolerances

Every 300 Blackout Rifle Barrel we produce undergoes rigorous, 100% individual testing. But long before this final step, each barrel starts as a 4150 Chromoly Steel blank - the same exact stuff the military uses in its service rifles. Each barrel is then precision-cut on a CNC machine, producing the most accurate rifling possible. All equipment and every fabrication process is monitored under ISO 9002 quality control metrics, guaranteeing a perfect barrel every time. What's more, each barrel is heat-treated to achieve a hardness rating of RC 28 to 32, creating the toughest and wear-resistant rifling inside perhaps the strongest 300 Blackout Barrel on the market

Unparalleled Accuracy, Guaranteed

Because our barrels are heat-treated and stress relieved, they offer superior rifling characteristics that'll outlast any other barrel on the market. This allows us to avoid the chrome-lining process, which can kill accuracy while providing just a slight increase in barrel life. Our heat treatment process and mil-spec 4150 Chromoly steel compensates for that, which results in a 300 Blackout Rifle Barrel that guarantees 1 MOA accuracy at 100 yards, though regular production testing has shown accuracy as high at 0.7 MOA.
