Best 300 Blackout Suppressors

When it comes to guns, you’ll find that many of them are louder than you expect, and while you’ll still want your own ear protection so your hearing isn’t damaged as you fire, it can also be a good idea to lower the volume for those around you as well. A good suppressor can make a big difference in dampening the sound, especially on a 300 Blackout rifle.

Of course, before you decide to buy a 300 Blackout suppressor, you’ll have to determine the legality of it where you are. For the most part, suppressors are legal in 42 of the 50 states (the exceptions being California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island). However, you should check with your local jurisdiction, as some of these have their own restrictions despite state laws.

Everyone’s needs are different so finding the best 300 Blackout suppressor can require a little research, based on your personal needs and the exact weapon you have. Because quality is one of the most important factors, you’ll want to make sure you choose one made of superior materials, such as steel or titanium. This will help withstand the beating of use and keep corrosion away.

Durability is vital when it comes to silencers because the purchase process is not short or simple. You don’t want to have to replace your suppressor frequently. Also, knowing that you have a suppressor that works on multiple firearms can help reduce this fiasco, since you won’t have to go through the grueling process multiple times. Start by choosing a suppressor that can handle the largest caliber (meaning it has the largest diameter) you feel you might need to accommodate, based on your array of firearms.

Because the 300 Blackout is a centerfire rifle, you’ll want to make sure you get the correct type of suppressor for this firearm. A silencer for a centerfire pistol or a rimfire suppressor won’t work for you. You may also want to find out about the point of impact shift caused by mounting the suppressor to your rifle, since you can’t use tilting block action with a rifle.

You’ll also want to consider the difficulty of mounting the suppressor to your muzzle. Also, consider just how much noise reduction you need. Most of the time, greater suppression is better, so take a look at how quiet the 300 Blackout suppressor makes your rifle prior to making a purchase. Of course, make sure that, when you settle on a suppressor you like, it’s rated for use with the correct caliber so that you can use it with your 300 Blackout rounds.
