Are Suppressors Legal?

The short answer: it depends. The long answer is that it would depend on the state that you live in. For the moment, they are legal in 42 states. Eight states: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island prohibit the use of suppressors.

Per 2019 Legality

Even if your state allows the use of suppressors, it would be wise for you to double check. Some jurisdictions might disallow the use of suppressors even if state law does not outlaw them.

To make sure your state is one of the 42 states where it’s legal to own and use a suppressor, you can consult this page for information.

How to Choose a .300 Blackout Suppressor

Knowing which .300 Blackout suppressor will be best based on your personal needs and preferences is essential. At the same time, you’ll need to consider a few factors that will play a role in your final decision. If this is your first time purchasing a .300 Blackout suppressor, you may want to pay close attention to what you should look for. The following are some aspects and features that you should look for:

Material

One of the most important things to consider when looking for a suppressor is quality. The level of quality will depend on the materials the suppressor is constructed from. Most of the time, materials like titanium or steel will be used by manufacturers. These are proven to take some serious beatings and will also have the ability to resist any kind of damage or corrosion.

Silencerco - Omega Suppressor Multi Caliber Quick Detach is made of titanium, stainless steel, and Stellite the Omega is both full-auto and magnum rated.

Installation

In order for a suppressor to work, it obviously has to be installed on the muzzle of your gun. Most of the products included here will likely be easy to install suppressors that won’t require any kind of tools or the skills of a professional gunsmith. Most are threaded to ensure quick attachment and detachment.

Noise Reduction

The lower the noise, the better. That’s one thing to consider when you’re looking for a silencer. Look for a silencer that will keep the noise of your gun below 140 decibels. At those levels, you can fire your .300 Blackout rifle without the aid of any ear protection.

However, if the noise levels appear to be a little too uncomfortable, you can still use ear protection. In fact, this may be recommended if you plan on using your .300 Blackout in extended shooting sessions.

Review of the Best .300 Blackout Suppressors

Below is a list of the best .300 Blackout suppressors currently on the market as of this writing. While the list will probably be subject to change within the next year, this is your opportunity to choose one of these products as one of your own.

Prior to purchasing, we hope at this point you made sure that you are free and clear of any possible legal headaches that may arise from purchasing or owning a suppressor. Once you're clear and blue skies for miles, you can check out this list below. With that said, let's get started with our list:

Pros

  • Very Accurate

First on the list, we’ll be taking a look at the Cyclone Suppressor from the Advanced Armament brand. This is a CNC-machined silencer designed to keep the noise of your .300 Blackout to a minimum. At the same time, you’ll experience a great deal of recoil reduction.

This is crafted from high-quality materials that are also designed to handle a great deal of heat that comes from continuously firing off shots.

At the same time, this is designed to reduce fouling and muzzle jump. If you think you need ear protection to fire off your .300 Blackout rifle, think again. This will reduce so much noise that it would be pointless to even consider using any type of ear protection.

If you’re looking for a suppressor for your .300 Blackout that is considered the best of the best so far, then look no further than the Advanced Armament Cyclone.

Bottom Line

This suppressor, for its part, does a great job suppressing the majority of noise. At the same time, it does a good job of reducing a lot of recoil and muzzle jump. So you get not only a good silencer, but also something that can double as a muzzle break. By the sounds of it, you're getting quite the total package. It’s no wonder why we gave it the honors for "best overall".

Pros

  • Very Silent
  • Reduces Recoil Considerably
  • Fits Easily on .300 Blackout Rifles

Cons

  • Might Be a Little Loose Upon Fitting. Adjustments Might Be Needed, if Possible

Next, we have the Gemtech GMT-.300 Blackout Suppressor. By the look of this, you’ll notice that this is a simple to assemble, easy to install suppressor. This is made from titanium G-core material to ensure the best in durability.

This also provides a quiet noise that can be hard to match when going up against other similar products. The important thing to note is that if you are able to get the sound of your rifle shots to about 130 decibels, you won’t have to use any type of ear protection.

This suppressor is guaranteed to bring it down to right around 36 decibels. Now that’s quite impressive. If you’re firing supersonic or subsonic .300 Blackout rounds, you’ll have an item hat can cooperate with both types of rounds.

If you’re looking for something like that, then the Gemtech might be the one to go for. Whether you’re hunting or want to stay covert in a home defense situation, this suppressor will have its uses when the situation warrants it.

Bottom Line

The impressive thing about this suppressor is its ability to keep your shots as quiet as possible. Even at sounds like 130 decibels or less, you can still do away with your ear protection while firing your rifle.

Pros

  • Super Durable
  • Installation is Easy
  • Reduces Rifle Noise Considerable

Cons

  • None

If you're on a budget, you'll be glad to know that you won't be left out in the cold if all you're doing is looking for a suppressor for your .300 Blackout. With that said, we bring you the Silencerco Omega Suppressor.

This is designed for multiple calibers and can be quickly detached. The Omega is constructed from stainless steel, titanium, and Stellite. In plain English, you're looking at one tough customer of a silencer.

If you're looking for something that will help you reduce a lot of noise on your .300 Blackout without having to break the bank, you probably would love to have a silencer like the Omega in your arsenal.

The good news is that it doesn't just work with .300 Blackout rifles, it can also fit other calibers like 5.56 NATO or the .223. This is practical and versatile and will work with most of these calibers. Not bad for something that is considered a "budget suppressor".

The design of this item features an anchor break. This is designed to give your .300 Blackout rifle a reduced amount of recoil and no muzzle jump. Of course, that will lead to better control and accuracy for your rifle. Imagine firing a rifle with little or no recoil or muzzle jump to work with. You’d be insane NOT to like that.

If you’re looking for a product that can also work like a muzzle brake, look no further than the Omega Suppressor as your best possible choice. It’s the best suppressor you can get at a price that will fit most budgets.

Bottom Line

In short, we’re quite impressed with this suppressor. And if you’re looking for something that will definitely do a great job at lessening the noise and reducing recoil, there’s no doubt the Silencerco Omega suppressor is your best option.

  • Reduces a Good Deal of Noise
  • Excellent for Most Applications

Next, we’ll be taking a look at a product from Operators Suppressor Systems. This product is constructed from high-quality materials that will make this suppressor a very durable piece to add onto your .300 Blackout rifle.

More specifically, OSS uses stainless steel, cobalt, titanium, and aluminum to make this silencer a very tough product that can handle every single round that you’ll fire off. In fact, you can expect this to be impervious to all kinds of weather, corrosion, and abuse. If you’re looking for a suppressor that is built to last a very long time, you’ll probably want to give this an even deeper look.

If you want the best in noise reduction, this item can reduce gunfire to right around 130 decibels. At this rate, you won't even need to use any kind of ear protection. You'll be right around the level of noise where it is safe to fire a gun sans earplugs.

This is interchangeable and can work with all kinds of calibers within the AR-style family. If you want a suppressor that's not just for your .300 Blackout, but also for an AR-15 or a Creedmoor rifle, you might want to put thisproduct to good use.

This silencer can also work with some muzzle brakes as well. If you pair this with an STS muzzle brake, you'll be able to experience not only the best in silent shooting, but also a great deal of recoil reduction and less muzzle jump. Put them together and they will stay on nice and tight the whole time you use your rifle.

Bottom Line

The OSS suppressor is worth the investment if you're looking for a suppressor that has the capability to be interchangeable and can also work with just about any AR-style rifle.

If you're satisfied with this one, you'll want to buy another one for any additional rifle you might have. That is, of course, if you decide that this suppressor is your best choice. For the best in quiet shooting and all around durability, the OSS suppressor may be hard to beat.

  • Easy to Attach and Detach.
  • Reduces Recoil Quite Considerably

Aside from that, this is a suppressor that will work with pretty much every single AR-style rifle including the .300 Blackout. This has the capability to deliver silent and deadly shots from mid-range or long-range. That, of course, depends on the rifle you use.

No doubt that this will also be useful with pretty much any activity for your .300 Blackout rifle. Made from Grade 5 titanium, expect this suppressor to be quite tough to deal with. This will handle just about any abuse, weather, or corrosion.

If you're looking for a suppressor that will last so long it will probably stick with you for years (or decades), then the Sig Sauer Suppressor could just be what you're looking for. This has the ability to reduce the noise of your shots to just approximately 137 decibels. This means you can fire off your rifle and still won't have to use ear protection.

Bottom Line

The Sig Sauer proves itself once again that they are a reliable brand to go with when it comes to guns and accessories. If you're the kind of gun owner that might look for a brand to rely on, give the Sig Sauer a try. You can start off by purchasing this suppressor if you so choose.

Can You Legally Make a Suppressor?
