Noveske 18" 5.56 Stainless Lo-Pro DDF EXTRA THICC SPR Barrel - .9375" Journal

When accuracy, durability, and thermal control matter most, the Noveske 18” Special Purpose Rifle Barrel delivers uncompromising performance. Designed for elite shooters and trusted by U.S. Special Operations personnel, this barrel combines cutting-edge engineering with combat-proven reliability.

Crafted from 416R stainless steel and hand-polished to perfection, the proprietary Noveske Match Chamber ensures consistent, match-grade accuracy. But the real innovation lies in the Disruptive Deep Fluting (DDF)—a revolutionary contour that reduces blast wave compression and sinusoidal resonance, resulting in tighter shot groups, faster cooling, and extended barrel life.

Backed by data from the 2024 TACOM HO FEA study and Noveske’s Combat Systems R&D, this barrel is more than a component—it’s a precision instrument. From the serialized QC tracking to the pinned low-profile gas block and extended feed ramps, every detail is optimized for performance under pressure.
