The Dead Air KeyMo Zero Mount in 9/16-24 RH is a lightweight quick-detach muzzle mount (brand part no. DA323) for shooters who want a faster, more repeatable attachment for a KeyMo-equipped suppressor. Dead Air Silencers cuts it from heat-treated 4140 chromium-molybdenum steel and finishes it in black nitride. The compact body enters the blast chamber less deeply, which holds weight down and supports sound performance. This is the 9/16-24 right-hand thread with a 9mm/.357 through bore, so it suits smaller-bore hosts with that thread. It works with Dead Air suppressors that carry a KeyMo or KeyMicro adapter.

Key Specifications

• The thread pitch is 9/16-24 RH, a right-hand thread, so it only fits a muzzle threaded to that size.
• The through bore is 9mm/.357, sized for projectiles of that diameter and smaller.
• The mount is made from 4140 heat-treated chromium-molybdenum steel, a hard alloy that holds up to repeated installation.
• The finish is black nitride, a surface treatment that adds hardness and corrosion resistance.
• Overall length is 1.385 inches, short enough to keep the suppressor close to the muzzle.
• Outside diameter is 1.08 inches, which sets the profile at the muzzle.
• Weight is 2.2 ounces, light enough that it barely changes the balance of the host firearm.
• The tool feature is a 3/4-inch wrench and socket flat, so it can be tightened with common tools.
• The mounting system is KeyMo quick detach, built for fast on and off with a KeyMo-equipped suppressor.
