The Dead Air KeyMo Zero Mount in 1/2-28 (brand part no. DA320) is a lightweight, minimalist quick-detach mount for the KeyMo system. Dead Air made it shorter than a full brake so it enters the blast chamber less, which helps sound performance and keeps overall weight down. Like every KeyMo and KeyMicro muzzle device, it lets the suppressor come off without carbon-locking onto the mount. It is the right pick for a 1/2-28 host that wants a fast, repeatable suppressor attachment and no extra brake.

Key Specifications

• The thread pitch is 1/2-28, so match it to your barrel before ordering.
• The through bore is 9mm/.357, sized to clear the bullet for that thread option.
• Overall length is just 1.385 inches, a short mount that keeps weight and length low.
• Weight is 2.4 ounces for this thread pitch, light enough that it hardly changes how the rifle carries.
• The outside diameter is 1.08 inches, slim enough to stay out of the way on the muzzle.
• It is machined from 4140 heat-treated chromium-molybdenum steel, a strong, durable alloy.
• The finish is black nitride, resisting wear and corrosion.
• The tool features are a 3/4 wrench and socket feature, so installation takes a common tool.
• It works with all Dead Air KeyMo and KeyMicro adapter-equipped silencers, so it joins the same quick-detach family.
