Dead Air DA110 KeyMicro Brake 1/2x36 9mm Black Nitride Muzzle Device

The Dead Air DA110 KeyMicro Brake transforms standard 9mm carbines and pistols into precision shooting platforms with measurable recoil reduction and muzzle control. This compact muzzle device serves dual purposes as both a standalone brake and mounting platform for Dead Air KeyMicro suppressors. Built from 4140 heat-treated alloy steel with black nitride coating, it delivers professional-grade durability in a lightweight package.

What Makes This Different

Unlike basic thread protectors or flash hiders, the DA110 incorporates Dead Air's KeyMicro mounting system with precision-machined brake ports. The asymmetrical port design redirects gases to counter muzzle rise while maintaining compact dimensions. At just 1.2 inches long, it adds minimal length while providing suppressor-ready capability that standard brakes lack.

Key Features

• KeyMicro mounting system for Dead Air Mask HD and other compatible suppressors
• 4140 heat-treated alloy steel construction with black nitride finish
• 1/2"-36 TPI threading for 9mm firearms
• Asymmetrical port configuration reduces muzzle rise and felt recoil
• Compact 1.2" length maintains maneuverability
• Wrench flats for secure installation and removal
• Compatible with AR-9 platforms, PCCs, and threaded 9mm pistols

Range testing demonstrates consistent 15-20% reduction in muzzle climb compared to bare muzzles on 9mm carbines. The brake performs effectively across grain weights from 115gr to 147gr, maintaining zero shift under 0.5 MOA when properly torqued. Competition shooters benefit from faster target reacquisition, while the suppressor mounting capability serves tactical and recreational users requiring sound suppression options.
