Dead Air Xeno Xero Minimalist Mount - 1/2X28

A lightweight micro QD adapter with a 9mm bore for Dead Air's Xeno mounting system.

The Dead Air KeyMo system has been popular for years for its simplicity. No need to turn lock rings or press ratchet latches. But the KeyMo is heavy and the muzzle devices tend to be on the long side. Dead Air is currently pushing the envelope in the lightweight suppressor world. Their new 3D printed titanium line is full of featherweight powerhouses. So why take an ultralight silencer and add 30% or more of its weight back for a QD system? Simple is light, simple is strong, simple is good. Dead Air proves simple can also be advanced with the Xeno system.

Product Deep Dive

The Xeno Xero is the smallest and lightest mount from Dead Air. Its innovative taper design, left-hand threads, and accessible tool features provide an optimal platform for accuracy, while still being tough enough to withstand hard use. This simple yet sophisticated mount takes the complexity out of maximizing your shooting capabilities. The Xeno system can be used on any HUB compatible silencer equipped with a Xeno Adapter (sold seperately). With its short length and 9mm bore, the Xero 1/2X28 mount is perfect for SMGs and other compact PDWs. The short length is also excellent for silencers with short blast chambers. A Xero looks great on bolt guns and is perfect for light contour barrels that don't have the muzzle diameter for 5/8X24 threads.

Dead Air's use of 4140 chrome moly steel is a deliberate choice to offer the best performance for long term use. Many manufacturer's use 17-4 stainless steel. While this is an excellent steel, it can gall if not treated properly. The nitride finish used on the Xeno gives excellent corrosion resistance and surface hardness for durability.

Dead Air also gives ample tool surfaces to work with. Many companies don't leave enough access to wrench flats to re-tighten or to remove a silencer or muzzle device while they are mounted.

What's different about the Xeno?

So why should you choose the Xeno system over something like a Q Plan B or Rearden Atlas? Great question, and we will never knock products from Rearden, but this Dead Air mount comes with some unique attributes.  You decide.

Dead Air built the Xeno to solve common problems seen in other mount systems. The biggest difference is the use of left hand threads. Left hand threaded devices have the unique advantage of being removed by turning the opposite direction used to tighten the muzzle device to the barrel. This prevents the muzzle device coming off inside the silencer when it is removed due to the silencer being turned in the direction that would tighten the device to barrel.
