Dead Air DA123 Xeno Muzzle Brake 1/2x28 Black Nitride 4140 Steel

The Dead Air DA123 Xeno Muzzle Brake transforms standard AR-15 platforms into precision shooting systems while serving as a quick-attach mounting point for Dead Air suppressors. This dual-purpose brake reduces felt recoil and muzzle rise significantly compared to standard A2 flash hiders.

What Makes This Different

The Xeno mounting system sets this brake apart from traditional muzzle devices through its proprietary quick-detach interface. While standard brakes only manage recoil, the DA123 provides suppressor compatibility without sacrificing performance. The black nitride finish offers superior corrosion resistance compared to standard phosphate coatings, extending service life in harsh environments.

Key Features

• Quick-detach mounting system compatible with Dead Air Xeno suppressors
• 4140 steel construction with black nitride finish for maximum durability
• 1/2"-28 TPI threading fits standard AR-15 barrels and similar platforms
• Multi-port design reduces recoil impulse and muzzle climb effectively
• Precision machined tolerances ensure consistent suppressor alignment
• Wrench flats machined for easy installation and removal
