The CMMG ZEROED 46 raw stainless suppressor handles .45 caliber and smaller centerfire pistol and rifle cartridges in bare, heat-treated 17-4 stainless steel (CMMG part no. 11DB064). The uncoated finish starts out a smoky bronze color and ages with use, so no two cans end up looking the same. It is 6.5 inches long and 18.3 ounces with a mount, and it carries a full-auto rating. A 1/2-inch square drive on the fixed front cap takes a ratchet or breaker bar for leverage when you change rear HUB mounts. It is a strong fit for a .45 ACP, 10mm or .40 S&W host that will share the can with a rifle.
