The CMMG ZEROED 36 is a .36 caliber/9mm centerfire suppressor with direct thread attachment (CMMG part no. 11DB030). CMMG describes it as overbuilt by both pistol and rifle suppressor standards, at home on 9mm or smaller pistol calibers and on cartridges up to 350 Legend and 8.6 BLK. The heat-treated 17-4 stainless body is tubeless with laser-welded baffles and a nitride finish. Two direct thread HUB mounts come in the box, so it fits both common thread pitches. It suits a shooter who wants one can for a 9mm carbine and a rifle.

Key Specifications

• Overall length is 6.5 inches with the mount and 6.2 inches without it.
• Weight is 17.1 ounces with the mount and 15.1 ounces without it.
• Body diameter is 1.58 inches, a size that clears most handguards.
• Construction is heat-treated 17-4 stainless steel with a tubeless, laser-welded baffle design.
• The finish is nitride, a surface-hardening treatment that resists corrosion and cleans up easily.
• It is full-auto rated, with CMMG noting approximately 240 rounds between cooldown periods.
• The box includes one 1/2-28 and one 5/8-24 direct thread HUB mount, covering the two most common barrel threads.
• The body is 1.375-24 HUB compatible, so a QD mount and muzzle device system can be added later.
• A 3/8-inch square drive in the front cap and 7/8-inch wrench flats on the mounts let common tools handle mount changes.
