CMMG 11DB026 Zeroed 46K 45Cal 1.58" Black Stainless Steel

The CMMG ZEROED 46K is a compact .45 ACP suppressor built for shooters who need effective sound reduction without sacrificing overall rifle or pistol length. Measuring just 5.5 inches long and weighing 15.3 ounces, this direct-thread suppressor delivers serious noise reduction on .45 caliber and smaller centerfire firearms while maintaining the durability and ease of use that define CMMG's suppressor line. Whether you're running a .45 ACP pistol, .45-caliber rifle, or PDW, the 46K offers a balanced approach to suppression for tactical, hunting, and range applications.

Built from heat-treated 17-4 stainless steel with a nitride finish, the ZEROED 46K resists corrosion and cleans easily with standard solvents or ultrasonic cleaners—no special maintenance gear required. The full-auto rating means it can handle sustained fire, though expect to observe cooldown periods during prolonged shooting. Like all CMMG suppressors, the 46K is machined and assembled entirely in-house, giving you confidence in quality control and consistency from round to round.

Attachment flexibility is a major win here. The suppressor ships with both a 5/8"-24 and .578"-28 direct-thread mount, covering most common .45 ACP platform thread pitches. The 1.375"-24 HUB-compatible design means you can swap to any manufacturer's QD or direct-thread HUB mount down the road if your setup changes. Disassembly uses standard tools—7/8" wrench flats on the direct mounts and a common 1/2" square-drive ratchet on the end cap—so you're not hunting for proprietary wrenches.

Before ordering, confirm your firearm's specific thread pitch and barrel length requirements. The 46K is rated for .45 ACP with no minimum barrel length restriction, but other calibers may have different minimum requirements.

Frequently Asked Questions

What .45 pistols and carbines will this suppressor work on?

The CMMG ZEROED 46K is chambered for .45 ACP and smaller centerfire rounds. It ships with 5/8"-24 and .578"-28 direct-thread mounts, which cover the vast majority of .45 ACP platforms. Confirm your firearm's thread pitch before purchase; if it uses a different thread pattern, you'll need to purchase the appropriate direct-thread or HUB mount separately.

Can I use this suppressor on other calibers besides .45 ACP?

Yes. The 46K is rated for .40 S&W, 10mm, 9mm, 5.56x45mm, 7.62x39mm, .300 BLK, and numerous other centerfire cartridges. Always verify that your specific caliber and firearm are compatible with the suppressor bore and your barrel's thread pitch.

What comes in the box?

Each CMMG ZEROED 46K includes the suppressor, one 5/8"-24 direct-thread mount, and one .578"-28 direct-thread mount. If your firearm requires a different thread pitch or mounting system (such as a QD HUB mount), you will need to purchase that separately.

Do I need special tools to take apart and clean this suppressor?

No. The direct-thread mounts have 7/8" wrench flats for easy removal with a standard wrench. The end cap accepts common 1/2" square-drive ratchet wrenches and breaker bars. The suppressor can be cleaned with nearly any solvent or in an ultrasonic cleaner without concern for finish damage.
