Take the Heat

A suppressor’s job involves a lot of hot gas. That is to say that they take a lot of abuse as they do their job of eliminating some of the sounds of a fired shot. The main takeaway here is that prioritizing durability in a suppressor is an important factor in winding up with a high-quality suppressor. Just about everyone knows that titanium is a very strong type of metal.

Luckily, many suppressors are made from titanium alloys and those are a great option to consider. Titanium also has the benefit of being lightweight and corrosion-resistant. It can easily stand up to those abusive conditions suppressors encounter during every trip to the range.

Screw It On

If you are going to be investing in a suppressor, it is important to make sure that your rifle is ready and able to have a suppressor installed on it. Having a threaded barrel is common especially if you planned while building or buying your .300 Blackout rifle. If your barrel isn’t threaded, the waiting period for a suppressor stamp is a great time to have it taken care of. That way you’ll have no hurdles to clear once you finally obtain your chosen suppressor. Just make sure you have the tools and know-how required for proper installation. An incorrectly attached suppressor is just asking for trouble.

Sound Bites

When was the last time you took a good look at your hearing protection gear? It might sound counterintuitive to mention when talking about suppressors, but it is important to continue to prioritize hearing protection even with a suppressor. Suppressors in real life don’t work like they do in the latest action movie. Hearing damage can still occur while shooting a suppressed rifle and that is a sense you can’t get back. Make sure your hearing protection gear is up to par even with your newly suppressed rifle.

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.

If you’re looking to be the silent, but deadly hunter or if you want to be as quiet as possible when taking on home invaders and prowlers, the Gemtech suppressor might just be exactly what you’ll need.

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.

How to Choose a .300 Blackout Suppressor

Knowing which .300 Blackout suppressor will be best based on your personal needs and preferences is essential.

If this is your first time purchasing a .300 Blackout suppressor, you may want to pay close attention to what you should look for.

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.

People Also Ask

In order to make the search for your next .300 Blackout suppressor easier, it is important to consult these frequently asked questions. This will clear up any possible concerns you may have while looking for a suppressor of your choice. Here are the following questions:

Do Gun Suppressors Wear Out?

The short answer: it depends. The long answer: it will depend on how old the suppressor is. These days, most of the modern suppressors won’t be able to wear as easy as old school suppressor. At the same time, if your suppressor is tight and secure, it won’t be susceptible to any quick wearing.

Can Any Gun Have a Silencer?

Yes. However, the silencer has to be threaded a certain way to fit the gun it was designed for. So in essence, some silencers can be designed for certain types of handguns. Likewise, the same can be done for certain types of rifles as well.

Are Silencers and Suppressors the Same Thing?

Yes. The only difference is the name. Silencer is more so the legal way of saying suppressor. However, the latter is more of a technical term. Either way, you can call it whatever you want.

Can You Legally Make a Suppressor?

Yes, you are able to legally make a suppressor. Just make sure that you follow the rules and guidelines as if you were making a legal and registered firearm as approved by the NFA. Remember, it may also depend on any laws and regulations in your locale or state. Once again, err on the side of caution and check the laws in your jurisdiction to ensure that you are free and clear of any legal messes that may arise.
