Our 10.5" Heavy Pistol Barrel chambered in 300 Blackout offers you, the at-home AR builder, the opportunity to piece together a whisper pistol that perfectly balances a compact size, accuracy, weight, and durability. With our superior manufacturing process and mil-spec 4150 Chromoly steel construction, your 300 Blackout Pistol or SBR will provide the performance you require in a form-fit package, and it's all available for a great price. Here, affordable doesn't mean cheap.

Mil-Spec Construction for Better Performance

We only use mil-spec 4150 Chromoly Steel in our pistol barrels because it's the best steel available on the market, the same stuff the military prefers in its service rifles. Every barrel blank is fabricated to extreme tolerances using CNC machinery and ISO 9002 quality control standards. Every barrel is heat treated for superior durability and resistance to wear, and every barrel undergoes a thorough individual inspection. The end result is a more accurate, reliable barrel with longer life and better performance.

Better Accuracy and Barrel Life

The secret is in our steel, precision rifling cutting, and heat treating processes. By using the best barrel steel available, precision-cutting it using CNC machinery, and heat-treating every barrel to a hardness rating of RC 28 to 32, we produce a barrel that doesn't require chrome lining or additional treatments. This reinforced barrel resists wear and tear better, while its hardened rifling provides better accuracy, more consistency for performance, and as much barrel life as a chrome-lined barrel with proper care. Because we don't use chrome lining, you save money in the end, without sacrificing any performance.
