DEADAIR DA121GOV XENO GOV A1 FLASH HIDER 1/2-28

The Dead Air Armament Xeno GOV A1 flash hider in 1/2-28 is a serious muzzle device built for shooters who demand precision alignment and genuine flash reduction without unnecessary bulk. Whether you're running a precision rifle at the range, a duty gun, or a tactical build, this 17-4 stainless steel flash hider delivers repeatable performance and corrosion resistance in a compact package that won't add length to your barrel.

The GOV series distinguishes itself from Dead Air's standard Xeno line through material—nitride-coated 17-4 stainless steel replaces the standard nitrided 4140, giving you superior resistance to corrosion and erosion. That matters if you're shooting suppressed and want your muzzle device to hold up to the unique environment inside a can, or if you're running this in harsh conditions where rust is a real threat. The large taper and thread-behind-taper design ensures the flash hider seats repeatably every time, so once you dial in your point of impact, it stays there even through sustained fire.

At just over 2 inches long and weighing 3.36 ounces, the Xeno GOV A1 keeps your rifle's profile tight without sacrificing effectiveness. The minimalist design cuts flash without the complex baffle geometry some competitors rely on, and the 3/4-inch wrench feature makes installation and removal straightforward—no proprietary tools needed. Compatible with both Xeno GOV and legacy Xeno adapters, this flash hider slots into an existing suppressor system or works standalone.

Frequently Asked Questions

What is the difference between the Xeno GOV and standard Xeno muzzle devices?

The primary difference is material. The GOV series uses nitride-coated 17-4 stainless steel, which offers superior resistance to corrosion and erosion compared to the standard nitrided 4140 steel found in the regular Xeno line. If you're running suppressed or in harsh conditions, the GOV's material upgrade pays dividends.

Yes, the Xeno GOV A1 is compatible with both Xeno GOV and legacy Xeno adapters, so it integrates with Dead Air's suppressor ecosystem. It also works as a standalone flash hider on any 1/2-28 threaded .30 caliber barrel.

What tools do I need to install and remove this muzzle device?

The Xeno GOV A1 features a 3/4-inch wrench feature, so you'll need a standard 3/4-inch wrench for installation and removal. No proprietary tools required.

How long is the Xeno GOV A1 flash hider?

The overall length is 2.16 inches, keeping your barrel profile compact and your rifle's handling tight without sacrificing flash reduction performance.
