The Dead Air KeyMo Zero Mount in 11/16-24 is a lightweight, minimalist quick-detach muzzle mount (brand part no. DA324) that gives a KeyMo-equipped suppressor a faster, more repeatable way onto the rifle. Dead Air Silencers machines it from heat-treated 4140 chromium-molybdenum steel and finishes it in black nitride. Its short body sits shallower in the blast chamber, which keeps overall weight down and helps sound performance. This is the 11/16-24 thread pitch with a .458 through bore, so it is built for the larger-bore hosts that use that thread. It works with Dead Air suppressors that carry a KeyMo or KeyMicro adapter.

Key Specifications

• The thread pitch is 11/16-24, so the mount only fits a muzzle threaded to that size.
• The through bore is .458, sized for projectiles up to .45 caliber.
• The mount is made from 4140 heat-treated chromium-molybdenum steel, a hard alloy that stands 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 1.9 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.
• The suppressor comes off without carbon-locking onto the mount, as with all Dead Air KeyMo and KeyMicro muzzle devices.
