Why Use a Suppressor?

It makes your gun quieter! Next question, please. Seriously, though, this is more important than you might immediately realize.

Yeah, a lot of times, you still wear hearing protection, but a suppressor can actually bring shooting down to a hearing safe level. This is really convenient.

Silencer Central Banish 30 Shooting Right Side
You might still choose to wear ear pro, but with a suppressor, things are a lot quieter.

A suppressor can also reduce recoil and muzzle blast. And it’s great for hunters who want a more natural sound when in the woods, as well as those that want to preserve their hearing for years to come.

Finally, there are the other benefits you get during hunting season, assuming your state allows hunting with a suppressor.

Come here silly wabbit…

Aside from being easier on your ears, you’re also doing a lot less to spook the local game animals, both the ones you might be shooting at and the general population.

I’ve seen hogs shot with suppressed .300 BLK and .308 Win rounds take off running, leaving the herd standing around looking confused. This makes follow-up shots possible where they wouldn’t have been before.

Choosing a .30-Caliber Suppressor

So, if any of that sounds interesting, how do you go about choosing a .30-caliber suppressor?

 There are actually a few things you need to keep in mind.

Caliber Compatibility

First, a lot of people go with a .30 or .45-caliber suppressor because they generally work with smaller calibers as well.

So, most .30-caliber suppressors will also work with, say, .22-caliber rounds like .223.

PMC Bronze .223 55gr
A sprinkling of .223

Small caveat…not all suppressors are built equally, so this might not apply to every model on the market. Sometimes you need a specific adaptor to make this jump to a smaller cartridge.

Long story short, make sure the suppressor you get is actually rated for the calibers you want. This is particularly important with Magnum calibers like .300 Win Mag, for example.

Left to Right .308 Winchester, 30-06 Springfield, .338 Winchester Magnum, .300 Winchester Magnum, .375 H&H Magnum
Left to right: .308 Winchester, 30-06 Springfield, .338 Winchester Magnum, .300 Winchester Magnum, .375 H&H Magnum

Attachment Method

Next, we need to look at how your suppressor actually attaches to your gun. In most cases, you want something with quick-detach lugs, a.k.a. QD.

These sport a discrete adaptor or muzzle device that threads onto the barrel. Then the suppressor attaches to the adaptor or muzzle device.

This is much faster to set up and take down than a direct-thread option where the suppressor screws straight onto the muzzle.

But a direct-thread option is often cheaper. They also may not require the adapter setup or special muzzle device that a QD option will.

Silencer Central Banish 30
Silencer Central’s Banish 30 is a direct thread model.

So, you do you.

In general, we feel the QD options are worth the marginal extra expense and the muzzle brake/comp you get as a base still works well even with the suppressor attached.

Sound Dampening Performance

This one is pretty easy. How quiet does the suppressor you’re looking at actually make the round you want to fire? Does it bring it down to a hearing-safe range?

Are you okay with wearing ear pro if not?

Putting on Eye and Ear Protection

Are you willing to pay extra to have more sound baffling for even less noise?

Only you can answer these questions, so just make sure to compare the decibel reduction of each suppressor. Also, don’t trust any suppressor you can’t find a decibel rating for.

Monocore vs. Stacked Baffles

The inside of a suppressor contains structures called baffles. These diffuse and redirect the expanding gases, slowing and cooling them before they leave the muzzle.

This, in turn, makes the gun quieter.

Transparent suppressor

There are two different types, independent stacked baffles and solid monocore baffles.

Stacked baffles consist of individual pieces stacked together to form the interior of the suppressor.

Meanwhile, a monocore suppressor uses one long single piece inside.

Functionally, one isn’t necessarily better at reducing sound than the other. That said, stacked baffles are easier to clean, which is better for you when it comes to maintenance.

Monocores are easier to machine, which means cheaper price tags.

The key is figuring out what means more to you – price or ease.

Buying a Suppressor

It’s worth noting that as you evaluate prices for each of the suppressors below, you also need to factor in the $200 tax stamp.

Yep, because these devices fall under the National Firearms Act, there’s a process you must undertake to own one.

Suppressor ATF Stamp
Gotta have that tax stamp to legally own a suppressor.

This includes filing the correct paperwork, cutting the ATF a check for $200, and waiting a few months for the ATF’s okay.

Best .30-Caliber Suppressors

Alright, with all that out of the way, let’s talk about the best .30-cal suppressors on the market.

The following list consists of suppressors we like the most out of all our testing. Many of us here at PPT either have the following models or at least have experience with them via media events and industry range days.


We realize this list does not encompass every .30-cal can on the market, but frankly, there’s not enough space to talk about them all. So, we’ve limited our list to some of our personal faves.

In no particular order…

1. Dead Air Sandman-S

The Dead Air Sandman-S is a monocore suppressor with a QD mount for easy attachment and removal.

It is just a hair under 7 inches in length, weighing in at 18.5 ounces. Rated for up to .300 WM and .30-06, larger .30-cal stuff is no problem for it whatsoever.

Dead Air’s Sandman-S also features a removable front-cap with a built-in flash hider.

Having a replaceable part on the end of your suppressor is great…but why?

Well, if you drop it or otherwise damage it, you don’t have to replace the whole can. You’re only out the end cap, which Dead Air sells and can ship right to your door.

User reports put the Sandman-S at around 140dB. MSRP on the Sandman-S comes in at around $1,069.

4. Q Trash Panda

Meme name aside, Q’s Trash Panda offers some serious performance.

Q is run by Sig and AAC alum Kevin Brittingham, and it’s clear he’s brought both his engineering chops and design experience to bear here.

Despite its size, the Nomad-30 still offers impressive sound dampening and compatibility with a number of Key Mount Flash Hiders and muzzle brakes, as well as multiple quick-detach systems.

It is also extremely modular, with multiple front caps available, so you can get better performance out of smaller calibers. Just remember to take that 5.56 end cap off before you send a .300 WM round down the barrel, or you’re gonna have a bad time.

Dead Air Nomad 30

The Nomad-30 is reported to offer a decibel rating of 126.7dB.

Retailing for $969, the Nomad graces our list as the most affordable option.

If you’re looking primarily for a .300 AAC Blackout suppressor…buy the Gemtech 300BLK. Seriously, this is the one you want.

The sound suppression out of this thing is absolutely phenomenal and can drop .300 BLK into hearing safe ranges. (Still wear your ear pro, though, kids. They can’t transplant eardrums yet.)

Gemtech’s GMT-300BLK measures 6.7 inches in overall length with a weight of 14 ounces.

    I feel like there should be a shoutout to Pew Science here, since they have a very helpful set of metrics that people can use to evaluate things like quiet for user versus for quiet for bystanders. It’s an invaluable, quantitative, and standardized measure I used to buy my first .300 can.

      Not worth it. No sound reduction ratings are listed for any of Witt's suppressors on their web site. Poor quality in manufacturing. Poor customer service. Reviews show that their suppressors don't reduce sound levels like the pricier competitors. See YouTube for more data.

    I just purchased a Banish 30 so I won't have any actual experience using it for about a year but hopefully I'm happy with it. I went with it because of the serviceability, size/weight and the fact that they handle all the paperwork for you!!!! You simply can't put a price on that.

    I went with the one and done option, the Omega 36M. I like using the short config on my 8" 300blk home defense gun. Works great on my 5.56 rifles as well.
