Things to Look For When Picking Suppressors

things to consider


Suppressors need to be attached to your gun’s muzzle for it to become operational. Most of them are welded, CNC machined, or threaded to ensure durability and rapid mounting and detaching on any guns. For non-threaded barrels, there are several ways to attach a suppressor

The suppressor we listed here incredibly easy to install, requiring no special training, skills, or professional assistance. It will do you a great favor if you choose a silencer that’s very easy to attach and detach on any gun or rifle, especially if you’re on the field and in need of speedy transition between firearms.


The material construction quality is an important consideration when buying a suppressor or silencer for your 300 Blackout. A suppressor made of titanium or steel is quite sturdy, resistant to recoil, and capable of handling heavy beatings.

You also need to consider the cartridge based on the internal diameter. Some of the most common cartridge options for 300 Blackout are 5.56mm NATO, 300 AAC Blackout, 7.62mm NATO, and 300 Winchester Magnum. Subsonic ammo is popular among shooters as it lacks loud cracks as compared to supersonic ammo.

Reduce Noise Output

The primary purpose of a suppressor is noise reduction to protect the shooter’s ears from damage.[1] Choose the best 300 blackout suppressor that can minimize noise to a significant degree. 

Look for a 300 blackout suppressor that can produce noise below 140 decibels. At this level, shooters can fire off a 300 blackout without putting on ear protection. 

However, if you intend to fire off your 300 blackout suppressor for an extended time or if the noise is still piercing and uncomfortable even though a silencer is already attached to your rifle, AR 15, or handgun, it is highly recommended to wear ear protection.


Blackout suppressors are generally not inexpensive. The most pricey ones are those made of titanium, followed by steel or stellite alloy, and then aluminum.

Upon purchasing a 300 blackout suppressor, you also need to shed money for the tax stamp, barrel threading, gun trust, shipping, and additional accessories.

If you buy a high-quality 300 blackout suppressor, the investment would be worth it as the benefits outweigh the cost. 


Aluminum suppressors are great for hunting elk or deer, while steel titanium or stellite is recommended for hunting hogs. If you’re intending to use one suppressor on multiple guns, purchase a model that is designed for the biggest ammo. 

Generally, 300 blackout suppressors are categorized into two attachment systems:

  • Direct thread system: It’s best for bolt-action guns. It doesn’t cause significant shifting in the point-of-impact, and it doesn’t require a separate muzzle device. It’s more accurate.
  • Quick-detach system: It allows fast and easy switching of suppressors from one gun or rifle to another. It’s ideal for tactical or competitive shooting. It’s more expensive than direct thread.

Length & Weight

A suppressor needs to be at least 8 to 12 inches in front of the muzzle for it to reduce noise levels effectively. Generally, longer barrels are quieter than shorter barrels.

A heavy suppressor model weighs 20 ounces or more, while a light model weighs around 12 ounces. 

Heavier suppressor models with a thread-on attachment system are great for one long-range bolt-action rifle. They are tough and can take severe beatings. An example would be the Cyclone Suppressor. Since they are heavy, they can add more weight to the riffle’s barrel, which can cause a shifting of zero when shooting the gun without the suppressor.


Lighter suppressor models are best for use on many guns, rifle platforms, and non-magnum calibers. They are less likely to affect the gun’s point-of-impact. Those made of titanium are both lightweight and strong, but they are costly.
