Simply put, if you require the most accurate 10.5" 300 Blackout Pistol Barrel for your AR build, look no further. Featuring the industry's highest rated stainless steel and extreme manufacturing tolerances, our 416R barrel boasts superior accuracy and performance of any sub-16" barrel. A nominal 1:7 twist rate offers the perfect balance of reliability and accuracy, whether shooting lightweight, supersonic loads, or heavy, subsonic loads.

The Best Barrel Steel on The Market

Stainless barrels generally receive top remarks for accuracy, but not all stainless barrels are created equal. Other manufacturers often use less desirable 416 standard or 410 stainless steel, which provides less machinability and performance. Our 416R steel contains fewer sulfate impurities which would otherwise cause rifle wear, deformation, and eventual failure to function reliably and accurately. Every barrel blank undergoes exact rifling cutting using quality CNC machinery, and every fabrication step is held to strict ISO 9002 quality control standards. Each finished barrel is hand-inspected thoroughly to ensure our reputation for accuracy is packaged inside every barrel.

Unparalleled Accuracy and Durability

Even though 416R stainless steel is the best material for barrel making, we take it a step further. Every finished barrel is heat-treated to achieve a hardness rating of RC 28 to 32, then stress relieved to balance rigidity and durability. This heat treatment process hardens the barrel's steel and rifling, providing even more accuracy and consistency, as well as longer barrel life.
