SKU: B300PM414.517(P)

Our 14.5", contoured 300 Blackout Rifle Barrel with 1:7 twist rate provides the perfect balance of weight savings, and the ability to provide greater accuracy with lighter, supersonic 300 Blackout loads (vs. 1:8 twist) without sacrificing stability in heavier, subsonic loads. Manufactured to extreme tolerances under our ISO 9002 quality control measures, every barrel rolls off the production line providing 1 MOA of accuracy at 100 yards (if you have the skill, that is). This barrel's perfect for building a 300 Blackout SBR. It's also great for pinning an extended flash hider or suppressor to make it a legal rifle, while providing a slightly more compact profile compared to a 16" barrel.

Better Reliability and Barrel Life

Our 300 Blackout Rifle Barrels are manufactured using mil-spec 4150 Chromoly Steel, the same stuff the military uses to build its own M4s and M16s (many other manufacturers use softer 4140 steel to reduce cost). But our barrels are even better, still: All rifling is CNC cut, then each barrel is heat treated to a hardness rating of RC 28 to 32. Every barrel is then stress relieved to provide unmatched rifling hardness for the ultimate strength and barrel life.

Providing Better Accuracy

Our barrels are not chrome-lined, and that's a good thing. We've combined the best of both worlds by avoiding this extra treatment. Chrome lining can provide additional rifling protection for longer life, but it reduces accuracy. We address this by our heat treatment process. Our rifling is simpler harder and stronger, negating the need for chrome lining. Because of that, our barrels combine better barrel life and better accuracy more effectively than any chrome-lined barrel.
