This particular 300 Blackout Rifle Barrel provides the best combination of rigidity and light weight of any 300 Blackout Rifle Barrel you'll find. By combining our traditional 4150 Chromoly heavy barrel with straight fluting, we get a 16" rifle barrel that's rock-solid compared to any M4 or contoured profile, and more rigid but lighter than any regular heavy barrel, even still. All these features and design work together for better maneuverability and superior accuracy with any supersonic or subsonic 300 Blackout load.

Precision Rifled and Fluted

Every 300 Blackout Rifle Barrel we sell - including this one - is built under the strictest manufacturing tolerances. All rifling is cut using a controlled CNC machine and ISO 9002 quality control metrics govern all equipment and the build process. Each barrel is 100% inspected for rifling and steel quality. We use only the highest quality gun steel: 4150 Chromoly, the same exact steel the military uses in its service rifles. Other companies use softer, weaker 4140 steel, but we don't cut corners here.

Better Accuracy and Barrel Life

We do not use chrome lining in our barrels, and this is a good thing. While chrome lining can provide extended rifling and barrel life, we go around that process and offer superior barrel life and harder rifling. By heat-treating our barrels to a hardness rating of RC 28 to 32 and then stress relieving the steel, we create more rugged, harder and stronger rifling that'll outlast any other barrel. Because the rifling is harder and free of chrome lining, it provides superior accuracy and reliability. We guarantee our barrels to provide below 1 MOA of accuracy at 100 yards (if you're a good shot). In fact, we've tested our regular production's accuracy and saw a reported MOA of 0.7 - less than 1" at 100 yards.
