Dead Air DA116 KeyMicro Brake Flash Hider 5/8-24 9mm Black Nitride

The Dead Air DA116 KeyMicro Brake Flash Hider combines muzzle brake performance with flash suppression capabilities in a compact package designed for 9mm carbines and pistols. This dual-function device reduces both muzzle rise and flash signature while maintaining the KeyMicro mounting system compatibility for seamless suppressor attachment.

What Makes This Different

Unlike traditional single-purpose muzzle devices, the DA116 integrates brake ports with flash-hiding geometry to deliver comprehensive muzzle control. The 4140 heat-treated alloy steel construction withstands sustained fire schedules that would damage aluminum alternatives. Black nitride coating provides superior corrosion resistance compared to standard phosphate finishes while maintaining precise dimensional tolerances for consistent suppressor alignment.

Key Features

• Dual-function brake and flash hider design reduces muzzle rise and flash signature
• KeyMicro mounting system ensures secure suppressor attachment with repeatable zero
• 4140 heat-treated alloy steel construction rated for full-auto fire schedules
• Black nitride finish provides enhanced corrosion resistance and wear properties
• 5/8"-24 threading fits standard 9mm carbines and pistol caliber carbines
• Compact profile maintains weapon maneuverability in tight spaces
• Precision-machined ports optimize gas flow for consistent performance

Field testing demonstrates measurable recoil reduction during rapid fire strings while maintaining flash suppression effectiveness in low-light conditions. The device performs reliably across temperature extremes from -40°F to 140°F without affecting zero shift. Competition shooters report faster target transitions due to reduced muzzle movement, while tactical users benefit from maintained night vision preservation.
