CMMG 11DB022 Zeroed 46 45Cal 1.58" Black Stainless Steel
$550.13
The CMMG Zeroed 46 is a direct-thread suppressor engineered to tame .45 caliber rifles and pistols while accepting smaller centerfire rounds as well. Built from heat-treated 17-4 stainless steel with a nitride finish, this suppressor delivers effective sound reduction without the weight penalty or complexity of proprietary mounting systems. At 1.58 inches in diameter and 6.5 inches long (without mount), it fits modern rifle and pistol platforms without excessive bulk. CMMG manufactures the Zeroed 46 entirely in-house, which means consistent quality control and a price point that doesn't require deep pockets.
What sets this suppressor apart is the no-nonsense approach to mounting and maintenance. It ships with both a 5/8"-24 and .578"-28 direct-thread HUB mount, so most common .45 ACP hosts are ready to run straight out of the box. The removable HUB mounts use standard 7/8" wrench flats—grab any socket wrench from your toolbox to attach or detach, no exotic tools required. The tubeless, laser-welded baffle design is equally straightforward: it cleans easy with common solvents or an ultrasonic cleaner, and the nitride surface resists corrosion even in harsh conditions.
The Zeroed 46 is also full-auto rated, capable of handling sustained fire with appropriate cooldown intervals (approximately 240 rounds between cooling periods). Beyond direct threading, it's HUB-compatible at 1.375"-24, so you can migrate to a quick-detach mounting system if your needs change. That forward-thinking design flexibility is rare in this price class.

Frequently Asked Questions
What mounting options come with the CMMG Zeroed 46?
The suppressor includes one 5/8"-24 direct-thread HUB mount and one .578"-28 direct-thread HUB mount. These cover most standard .45 ACP platforms. Before purchase, confirm your firearm's thread pitch and mounting requirements; if your host requires a different solution, you'll need to purchase the appropriate mount separately.
Is this suppressor compatible with other mounting systems?
Yes. The Zeroed 46 is HUB-compatible at 1.375"-24, so you can use it with any HUB-pattern quick-detach mount and muzzle device system of your choice. This gives you flexibility to expand your setup without replacing the suppressor.
Can I use this on full-auto firearms?
Yes. The Zeroed 46 is full-auto rated and designed to handle sustained fire with appropriate cooldown intervals (approximately 240 rounds between cooling periods).
How do I clean and maintain this suppressor?
The tubeless laser-welded design is straightforward to maintain. You can use nearly any common solvent or an ultrasonic cleaner. The nitride finish resists corrosion, so cleanup is simplified compared to bare stainless designs. Attachment and removal of the HUB mount require only a standard 7/8" wrench—no special tools needed.
