Noveske has introduced the Disruptive Deep Flute (DDF) barrel contour series for AR-15s, improving accuracy and extending barrel life by minimizing blast and resonance waves. Available in 5.56 and 6ARC, this innovation stems from a 2024 FEA study, enhancing performance while retaining a lightweight design used by U.S. Special Operations.
Noveske states “The Disruptive Deep Flute (DDF) is an external barrel structure designed to significantly reduce primary (blast compression and expansion) and secondary (sinusoidal resonance) wave events in barrels, improving accuracy, reducing heat, and extending barrel life. Using data from the 2024 TACOM HO Finite Element Analysis (FEA) study. Noveske’s Combat Systems Development & Support program launched an R&D project. The goal was to determine the optimal surface area per linear inch to effectively disrupt these wave events while maintaining the lightweight barrel contour already used by U.S. Special Operations personnel.”
Currently, Noveske Rifleworks is offering the DDF series in 5.56 and 6ARC and a N4 DDF upper receiver group.
