CMMG Zeroed 36 Suppressor and Plan B Mount

With so many suppressors entering the market lately, its becoming more difficult to stand out. CMMG has long made quality AR-style rifles, so it comes as no surprise that they joined the ranks of suppressor manufacturers. It should also come as no surprise that suppressors made by CMMG are optimized for the firearms they also make. Their CMMG Zeroed 36 suppressor is a multipurpose can with all the attributes a budding AR enthusiast might wish for.

The tubeless Zeroed 36 is manufactured from 17-4 stainless steel and laser welded giving it a robust structure designed to take a beating. Its 36 caliber bore makes it useful for a wide variety of cartridge compatibility. Basically anything from 9mm on down, which incorporates most of the firearms CMMG makes.

At the breach end of the can you will find the familiar HUB system that most manufacturers are moving to. With its 1.375-24 threads, you can use a huge variety of mounting solutions.

The Zeroed 36 originally came with a 1/2-28 direct thread cap, to which I added a 5/8-24 cap. More recently I’ve also added one of CMMG’s new Plan B mounts. Plan B is a mounting system that much like the hub system offers a homogenous mount that puts the sealing taper in front of the threads to keep them clean. Plan B mounts are available from most suppressor mount manufacturers (except maybe SilencerCo…😁😄 IYKYK).

There’s just enough of a little crunch feeling when the suppressor goes tight on the Plan B mount, that tension is what keeps the mount from coming loose. It takes a slight yank with your good hand to pop the can loose before threading it off the mount. 

There are, of course, other Zeroed suppressors in CMMG’s lineup with different bore sizes for different applications. For my purposes, the Zeroed 36 works well for 9mm, .308, 5.56, 6mm ARC, and 8.6 Blk. The variety of mounting options make it easy whether using the Plan B, direct thread, or a Nielsen booster for pistols.

The smooth nitrided exterior of the Zeroed 36 doesn’t offer much to grab ahold of, but it has a square 3/8 drive hole in the muzzle, to allow you enhanced purchase when changing out the hub. Like all Zeroed suppressors, the stainless steel Zeroed 36 is full-auto rated with an expected 240 maximum string recommendation.

As an unapologetic suppressor zealot, I was excited to get the zeroed 36 into my rotation. I rarely shoot without a can, so this one fits nicely into my collection. I initially used it on an SBR with both 5.56 and 300 BLK 11.5-inch barrels. It did a great job making them pleasant to shoot, with the 300 BLK being the preferred host. I noticed a bit of flash coming from 5.56 cartridges, which came as no surprise as there was likely a lot of unburnt powder hanging out in the baffles.

Later I used the can on a variety of different semi-auto rifles like my 20-inch 5.56 Desert Tech WLVRN, and a 16-inch AR build that I shoot a lot. I also used it quite a bit on some of my bolt action rifles in various calibers as well as on my 9mm pistols.

Shooting with the Zeroed 36 across a variety of firearms gave me an excellent opportunity to evaluate its benefits. I’ve had this can for a few months now and have put a lot of rounds down range from a wide variety of platforms. It’s been with me on many outings, range trips and hunts. I’ve been able to compare the report of this can compared to many others I’ve shot alongside it, both on a dedicated rifle range as well as in open high country.

The Zeroed 36 has a great tone with the traditional pssssssssttt sound that we are used to. Its heavier steel construction seems to soak up a good deal of the heat generated, which makes it pretty quiet even on smaller cartridges that don’t match the bore size. Subsonic rounds like the 300 BLK and 9mm don’t heat it up much, even after a full magazine. That makes for a pretty quiet report.

My 8.6 BLK, on the other hand, has a bit more gas volume. It seems to do better with suppressors that haver a larger internal volume. I expect the .338 ARC on the other hand would do fantastic with this suppressor using subsonic loads. All the supersonic cartridges I’ve tried have sounded pretty similar, and what I consider to be hearing safe. Of course, my family would tell you I’m deaf so keep that possibility in mind.

Point of impact changes have been minimal. The added buffering of the muzzle blast seems to help the bullet leave in a more stable situation, giving it a smoother flight. The added weight of the can on the rifle also helps keep the rifle steadier as it recoils.

This also helps reduce felt recoil a bit, thanks to both the added weight and the slowing of escaping gas pressure. I found that all of my rifles had a lower level of felt recoil when shooting with the Zeroed 36, as you’d expect.

Handguns, on the other hand, showed a slight increase in backpressure, which seemed to make the action operate faster. That gives the impression of added recoil, but I think it’s due to the sensation of higher slide speed. On many of the semi-auto rifle hosts, I was expecting some backpressure, but perhaps because of the Zeroed 36’s larger bore size, there was little noticeable gas coming back at me while shooting.

Overall the CMMG Zeroed 36 is a great little suppressor and with a very reasonable MSRP of $599.99. I paid more for my first suppressor and didn’t do half of the things this one does. That goes to show you how the suppressor market has improved in recent years.

If you’re searching for your very first suppressor now that tax stamps cost you nothing, the Zeroed 36 would be a good choice as it can be used on such a wide variety of host firearms. Most people, even novice gun owners will likely have a 9mm and .30 ocaliber rifle, which this suppressor can handle easily.

If I had to come up with a demerit for the CMMG can, it would only be its weight. It’s not terrible, but thanks to its stainless steel construction, it’s a little heavier than some other comparable cans I have. But if you want the full-auto lifestyle, you will likely be dealing with heavier suppressors like this.

I commend CMMG for bringing out a suppressor line that’s not made up of token entries. The Zeroed family of suppressors has you covered for everything from 5.56 dedicated cans all the way up to .46 caliber. They also have the shorter K-cans for those who love the short life.

Being from CMMG, I expect good service life and customer service should I ever need it. But so far, I don’t anticipate any issues with this suppressor. And I would certainly recommend it to anyone looking for an affordable, do-it-all can.
