Flux Defense today announced the Big Black Barrel, a 6″ replacement barrel engineered specifically for the Raider 365 to deliver maximum ballistic performance while preserving the platform’s compact size and function.

Key Features:

• Length: 6″ — sits flush with the Raider 365 chassis
• Caliber: 9mm
• Material: 4150 CMV steel (same base material used in machine-gun barrels)
• Finish: Black Nitride for enhanced hardness and corrosion resistance
• Performance: Increased velocity and softer felt recoil versus shorter barrels
• Compatibility: Exclusively for Sig P365 / Raider 365 — NOT compatible with Sig P320
• Branding: Flux Defense + True Precision

4150 CMV Strength and Exclusivity

Built from 4150 CMV steel and precision heat-treated, the Big Black Barrel offers superior tensile strength, toughness, wear resistance, and fatigue life compared with typical pistol-barrel steels. Combined with a Black Nitride finish, it delivers improved longevity, reduced friction, and consistent ballistic performance. Flux Defense is the only manufacturer producing a 4150 CMV replacement barrel specifically engineered for the Sig P365/Raider 365 platform.

“The Big Black Barrel gives Raider 365 owners a true performance upgrade — more velocity, softer shooting, and the durability you expect from 4150 CMV steel,” said Alex Aubrey, Chief Marketing Officer, Flux Defense. “We engineered this barrel to retain the Raider’s compact footprint while unlocking the most ballistic capability possible from a 6-inch configuration.”
