Introduction
CMMG has been upping their game since I first heard about them years ago, the brand is famous for AR-styled rifles, and has developed various improvements on the design with their Dissent and Banshee models. But having just finished up SHOT Show 2026, one of the biggest themes of the show is that EVERYBODY seems to be jumping in on the suppressor game. And I find no fault in CMMG for joining in on the trend, which brings us to today’s subject. We will be taking a look at the new CMMG Zeroed 36 Suppressor. A full-auto rated 35 caliber suppressor for use with cartridges like 9mm 308 Winchester and 8.6Blk.

The CMMG Zeroed 36 Suppressor
With so many interesting and diverse caliber offerings, it came as no surprise that CMMG started out with a broad selection of suppressor options. From rimfire suppressors made for 22’s, and 5.56 suppressors for your carbine. Up to big 30 caliber cans made to run on their 308 rifles, and even into the 36 and 46 caliber cans for those big bores. Our Zeroed 36 suppressor today is perfectly fitted for a host chambered in nearly any of today’s popular carbine calibers.

The Zeroed 36 uses the very popular hub-mounting system that most manufacturers are moving to. I can’t explain how much I appreciate this trend. As one who is used to having firearms rethreaded in order to use with my suppressors, its beautiful to not have that concern moving forward. The Zeroed 36 came with both a 1/2-28 and 5/8-24 thread cap for mounting to various firearms.

All Zeroed suppressors feature laser welded 17-4 stainless steel. You can feel when you pick these up that they are built robust, which is why it weighs over 17 ounces. Recommended full-auto use suggests breaks every 240 rounds or so. Its hub mounted design is accented by a 3/8 square drive hole in the muzzle-end of the suppressor, which allows you a solid disassembly option. Keeping with its modular design, no special tools are required for assembly or disassembly.
Shooting with the CMMG Zeroed 36
My first test with the Zeroed 36 was an indoor range, testing how it performed with 11.5-inch 300Blk and 5.56 semi-auto carbine. For that I used a Desert Tech WLVRN bullpup, switching quickly between to two calibers in the same rifle.

I also wanted to see how the Zeroed 36 would perform on bolt-action rifles. So, I would end up using it on several, my Desert Tech SRS in 6GT, and 8.6Blk. And I also brought along my Howa Mini and Taurus Expedition, chambered in 6ARC and 308 Winchester.

Shooting across all these host rifles, I used a variety of hubs to get the right thread pitch to fit each one. I even used my Breek Arms Tri-Lug mount, which makes a quick job of attaching and removal of the suppressor.

Modular Mounting
Making the Zeroed 36 a hub-compatible suppressor means there are countless ways to mount it. The can came with two direct-thread hub mounts, threaded 5/8-24 and 1/2-28 which will fit most firearms. I already had several other hub mounts already that I would also use. For shooting my Desert Tech SRS in 8.6Blk I would need a 3/4-24 threaded hub, I used a SilencerCo hub and it fit perfectly. Additionally I used my Breek-LOC QD tri-lug mount, which makes adding or removing the suppressor quick, sturdy and secure. The Zeroed 36 has a 3/8 square drive in the muzzle to give you a robust torque point for changing the hub system.

In total I ended up mounting the CMMG Zeroed to quite a variety of host firearms. A Desert Tech WLVRN SBR with 11.5-inch barrels in both 5.56 and 300Blk, and another WLVRN with 20-inch barrels chambered in 6 ARC and 5.56. To see how it did with 8.6Blk I fit the Zeroed 36 to my Desert Tech SRS A1 where it sounded great. For 308 I ran the suppressor on my Taurus Expedition 308 Winchester, a bolt-action featuring an 18-inch barrel. For 6.5 Creedmoor I installed the Zeroed can on a Bergara 22-inch HMR carbon.
Sound
Shooting a variety of firearms with the Zeroed 36 gave plenty of opportunity to evaluate its sound suppression. As you might imagine, it worked very well with low gas volume cartridges with big bores. When shooting the 9mm and 8.6Blk the Zeroed 36 can had more than enough volume to suppress the expulsion of gas to a reasonable level. Higher pressure cartridges like the 308 Winchester and .223 Remington gave the can a little more of a workout. Even so, the noise at the shooters ear was what I would consider hearing safe. Obviously according to authorities on the subject, you should always wear ear-protection, but the whole reason I own suppressors is to avoid that inconvenience.

Bolt-action rifles were perfectly suppressed by the Zeroed 36 can, whereas some of the semi-auto rifles were a touch louder. For example, using a Zeroed 556 can would have likely given better results when shooting 5.56 rounds. The larger muzzle of the 36 is less restrictive for the tighter column of pressure. And as usual, having a semi-auto ejection port near your face also brings the noise closer to your ears.
My overall impression with the report of the Zeroed 36 suppressor was good. It’s hard to make a modular suppressor that is perfect at everything, there always seems to be one compromise or another. I think this suppressor does a great job of offering the user options for various hosts and calibers. In the open country where I shoot it sounds fantastic.

Gas Blowback?
In our modern suppressor market, we are spoiled for choice. There are so many manufacturers, designs, and features you can get nearly anything you want. A very popular topic when it comes to suppressing semi-autos is the topic of gas blow-back. Semi-autos tend to push exhaust from the chamber back towards the shooter when suppressed. Many suppressor manufacturers have worked to reduce this back pressure to enhance your shooting experience with their suppressor. I shoot outside mainly, and my typical shot string isn’t particularly long. So this is not as big a deal for me, and I found the back-pressure caused by the Zeroed 36 to be acceptable. Some folks seem to be much more susceptible to blowback, and they might want to spend more money on something different.
This is obviously greatly dependent on the host firearm, for example shooting the Zeroed 36 on my bullpup rifles brings the ejection port even closer to your face than conventional rifles. It doesn’t bother me as I prefer the advantages of the design, but I can see how it might bother others.

For shooting the Zeroed 36 suppressor on a pistol, I chose my Ruger RXM 9mm. After installing a booster and piston into the back of the Zeroed can, it threaded nicely onto the pistol. It was a bit heavy for a pistol suppressor, but it worked great at keeping down the noise. There was of course a little added backpressure, but that is not uncommon.
