CMMG ZEROED 22 Suppressor – .22 LR, 1/2×28 Direct Thread, Black Features
The ZEROED 22 weighs 5.6 ounces and measures an inch across, which is what lets it ride on a rimfire pistol without turning the gun into a nose-heavy mess. Inside are 17-4 stainless baffles in a 6061-T6 aluminum tube, mounting 1/2×28 direct thread. Full-auto rated, and the whole baffle stack pulls apart for cleaning.
Our 16″ .22 LR upper assemblies come with 1/2×28 threaded barrels that match it directly, and the rest of what we carry sits under suppressors.

What is actually involved in buying a suppressor?
It is a Title II NFA item, so it will not ship to your home or even to a standard FFL. It goes to a dealer holding a Class 3 SOT. You file an ATF Form 4, pay the $200 transfer tax, submit fingerprints and photographs, and wait for approval before you can take possession. Approval times vary considerably.
Can I run it on a pistol as well as a rifle?
Yes, and that is much of the point of the one-inch diameter and 5.6 ounce weight. Any rimfire host with a 1/2×28 threaded muzzle will work, pistol or rifle. Just confirm your barrel threads really are 1/2×28 rather than a metric or 3/8×24 pattern before ordering.
Why does a rimfire suppressor need to come apart?
Rimfire ammunition is filthy. Lead, wax lubricant and unburned powder pile up on the baffles far faster than anything centerfire, so a sealed .22 can would eventually clog solid. The ZEROED 22 has removable end caps and baffles, with indexing marks so everything goes back in the right order and orientation.
What is the hex opening in the front cap for?
Carbon fouling can seize the front cap threads over time. CMMG cut a hex recess into the cap so a 1/4 inch Allen wrench or hex bit gives you real leverage to break it loose, instead of fighting it with a strap wrench and hoping.
What does full-auto rated mean on a .22 can?
It means the suppressor is built to take the sustained heat and rate of fire of automatic fire without coming apart. On a semi-automatic host it simply means you have margin to spare, so fast strings and long range sessions will not hurt it.
Can I own a suppressor in my state?
They are legal in most states but flatly prohibited in several, and a handful of others attach extra requirements. Your SOT dealer will know the rules where you live, and we cannot transfer one into a state that does not allow them. Check before you order.
