Dead Air DA120 KeyMicro Brake Flash Hider 5/8"-24 Black Nitride

The Dead Air DA120 KeyMicro Brake Flash Hider combines muzzle brake efficiency with flash suppression in a compact package designed for precision shooting applications. This dual-purpose muzzle device delivers measurable recoil reduction while maintaining low-light signature control for tactical and competitive use.

What Makes This Different

The DA120 integrates Dead Air's KeyMicro mounting system with proven brake geometry to create a versatile platform. Unlike standard linear compensators, this design features precisely angled ports that redirect gases to reduce felt recoil by approximately 15-20% while the closed-bottom design minimizes dust signature. The 4140 heat-treated alloy steel construction withstands sustained fire schedules that would degrade lesser materials.

Key Features

• KeyMicro mounting system compatible with Dead Air suppressor lineup
• 4140 HT alloy steel construction with black nitride finish
• 5/8"-24 TPI threading fits most .30 caliber rifles
• Dual-port brake design reduces recoil and muzzle rise
• Flash hiding geometry minimizes muzzle signature
• Closed-bottom design prevents ground disturbance
• Precision machined indexing for consistent timing

Field testing demonstrates consistent performance across various ammunition weights and powder charges. The brake ports effectively manage gas flow to reduce shooter fatigue during extended range sessions, while the flash suppression capabilities maintain low-light operational effectiveness. The nitride finish provides corrosion resistance in adverse weather conditions and simplifies maintenance protocols.
