DEAD AIR XENO GOV A1 FLASH HIDER 1/2-28 .30 CAL DA121GOV is the A1-style member of Dead Air’s more robust Xeno GOV family, built for shooters who want compact mounting, reliable alignment, and effective flash suppression in a simple, duty-oriented package. The Xeno GOV line uses a sleek, minimalist design that provides strong flash reduction while maintaining the repeatability and secure taper-mount lock-up that make the Xeno system attractive for hard-use rifles.

The GOV line’s main upgrade over the standard Xeno muzzle devices is material. This model uses nitride-coated 17-4 stainless steel, giving the part improved resistance to corrosion and erosion. Combined with the large taper and thread-behind-taper design, this gives the mount a strong case for shooters who care about precise alignment, dependable removal, and solid lock-up under repeated use.

The A1 profile gives you a more traditional flash hider geometry than the 3-prong version while staying inside the same Xeno GOV ecosystem. This flash hider is compatible with both Xeno GOV and legacy Xeno adapters, which helps if you are already invested in the Xeno mounting system and want flexibility across hosts and suppressor setups.

This DA121GOV variant uses 1/2-28 threads, a .30 caliber bore, measures 2.16 inches overall, has a .99 inch outside diameter, and weighs 3.36 oz. For shooters who want the more robust GOV material package in an A1-style Xeno flash hider, this is the correct 1/2-28 option.
