Are suppressors/silencers legal?

The short answer to this question is that it depends on the state that you live in. For now, they are fully legal in 42 states, while the 8 states, namely: California, Hawaii, Illinois, New Jersey, Massachusetts, New York, Rhode Island, and Delaware ban the usage of suppressors.

Even if you find that your state allows the usage of suppressors, it might be a good idea for you to double-check with the relevant authorities.

Factors to consider when buying a .300 Blackout Suppressor

When looking for a .300 Blackout Suppressor, you need to know what your personal needs and preferences are, as they would be essential in the decision-making process, just like any other times when you are choosing an accessory. Also, you should consider a few other factors besides your personal preferences which are just as essential.

If this is your first time buying a .300 Blackout suppressor, it might be a good idea for you to pay close attention to what you should be looking for.

Quality and construction

This is perhaps one of the most important factors to consider when looking for a.300 Blackout suppressor. The quality of a suppressor will largely depend on the materials that the suppressor is constructed from.

Most of the time, you will find materials such as titanium and/or steel to be used by most manufacturers. This is largely because these materials have proven over time that they can take some serious shootings before exposing themselves to any kind of corrosion or damage.

Installation process

This should be pretty obvious. In order for your suppressor to work, you’ve got to install them on the muzzle of your gun. Most products included here are easy to install and won’t require any kind of tools or a firearm expert to mount it on. Most of the products here are threaded to allow quick attachment and detachment.

Level of noise reduction

For suppressors, the rule of thumb is always ‘the lower the noise, the better’ as this should be the primary reason why you’re looking for a suppressor. You should look for a suppressor that is able to keep the noise of your gun below 140 decibels as at those levels, you can fire your .300 Blackout rifle without any ear protection.

That said, it’s always advised to use ear protection during extended shooting sessions with your .300 Blackout rifle, even with one of the best suppressors mounted on it.

Frequently Asked Questions

Q: Can any firearm mount a silencer?

The short answer is yes. However, the silencer needs to be threaded in a certain way to fit the gun it was designed for. Hence, in essence, some silencers could be designed only for certain types of pistols. And the same could be said for certain types of rifles as well.

Q: Are silencers and suppressors the same?

Yes. Perhaps the only difference between them is the name to it. A silencer kind of the ‘legal name’ for it, whereas a suppressor is more of a technical term. That said, both names are pretty recognized around the globe so you can call it whatever you want.

Q: Could you legally make a suppressor at home?

The short answer is yes. It is legal to make your own suppressor provided that you follow the rules and guidelines as approved by the NFA. You should also take note that this would depend on any laws and regulations on your local or state. Before making one, you should always double-check on the laws governing your jurisdiction to ensure you won’t get into any trouble.

Q: Do gun suppressors wear out fast?

The short answer to this is – it depends. It depends on how old the suppressor is. Thanks to technological advancement, most modern suppressors won’t wear out as fast as the more old school suppressors. If you want to prevent any quick wear and tear to your suppressor, make sure that it is tightly and securely mounted on your firearm before going for a shooting session.

Q: Do you really need a suppressor for a .300 Blackout rifle?

Well, you don’t really need a suppressor to be mounted on your .300 Blackout rifle to hit targets. But the .300 Blackout round was initially designed around the idea of being subsonic suppressed.

Q: Will a 300 Blackout suppressor work on a 5.56mm rifle?

A .300 Blackout or any other variant is also compatible with 5.56mm rifles.
