The CMMG Suppressor Zeroed 22 K is a compact, lightweight rimfire suppressor designed for shooters who want hearing protection without adding bulk to their .22 LR handguns or rifles. At just 4.5 inches long and 4.8 ounces, it's one of the smallest options available—light enough that you won't feel it on the muzzle, yet effective enough to noticeably reduce report on full-auto rated firearms. The 1-inch diameter is narrow enough that most pistols won't require suppressor-height sights, keeping your sight picture and ergonomics unchanged.
Built from durable materials—6061-T6 aluminum tube and front cap, 17-4 stainless steel baffles, and 4140 steel rear mount—the Zeroed 22 K is user serviceable from the ground up. The removable baffle stack, front cap, and rear cap come apart easily for thorough cleaning, and indexed baffle marks ensure you reassemble it correctly every time for consistent suppression. A 1/4-inch hex opening in the front cap lets you use a standard Allen wrench or hex bit to disassemble the unit, even if carbon has built up on the threads.
Attachment is straightforward: it threads directly onto any .22 LR firearm with standard 1/2"-28 muzzle threads. The hard-coat anodized finish resists wear and corrosion, and the suppressor is rated for full-auto .22 LR fire and semi-auto use with .17 HMR and .22 Magnum. Before purchase, confirm your firearm's thread pitch and mounting requirements; if your gun uses a different thread pattern, you'll need to source the appropriate adapter separately.

Frequently Asked Questions
Will this suppressor fit my .22 handgun or rifle?
The Zeroed 22 K threads directly onto firearms with standard 1/2"-28 muzzle threads—the most common rimfire thread pitch. Before you buy, verify that your firearm's muzzle threads match this specification. If your gun uses a different thread pitch, you'll need to purchase the appropriate adapter separately.
Can I use this suppressor on .22 Magnum or .17 HMR?
Yes, but with an important caveat: the Zeroed 22 K is full-auto rated for .22 LR, but only semi-auto rated for .17 HMR and .22 Magnum. Do not use it on full-auto firearms in those calibers.
How do I clean and maintain this suppressor?
The baffle stack, front cap, and rear cap are all removable, allowing you to disassemble the entire suppressor for thorough cleaning. Indexed marks on the baffles show you the correct order for reassembly. Use a 1/4-inch Allen wrench or hex bit in the front cap to help break it apart, especially if carbon has accumulated on the threads.
What comes in the box, and will I need to buy anything else?
The suppressor includes only direct-thread mounting hardware for 1/2"-28 threaded barrels. If your firearm has a different thread pitch or mounting system, you must purchase the appropriate adapter separately. Confirm your firearm's requirements before you buy.
