Best .300 Blackout Suppressors: Top 4 Expert Picks

The .300 AAC Blackout has been a popular rifle cartridge since its introduction by Advanced Armament Company (AAC) in 2011. Initially developed for the U.S. Army, the civilian market quickly discovered that the .300 AAC Blackout was an effective sporting load, especially for wild boar hunting.

Top 10 hunting gear

The popularity of this .30 caliber cartridge among coin hunters is astounding. Many night hunters use camouflage to approach their prey. Suppressors have become increasingly common in these groups to tame the wild muscle response of AR weapons. Suppressors are also popular with sport shooters and competitive shooters in target practice. Disconnected rifles are more comfortable for all participants to shoot with.

This article covers the major suppressors on the market for the .300 Blackout cartridge. In my reports, I will discuss construction, quality, design and performance. We hope this review will give you a better understanding of how to evaluate suppressors and what to look for in a suppressor for your weapon.

Legality issues

Before you consider buying a suppressor for your .300 Blackout rifle, determine if it is legal to have one where you live. The only way to be sure is to consult someone in your jurisdiction who is qualified to speak on this subject. In general, however, the laws on the possession of silencers are divided as follows.

Federal law

Possession of suppressors is legal under federal law, but is monitored and regulated by the Bureau of Alcohol, Tobacco and Firearms (BATF). You must contact the BATF to get a tax stamp for each suppressor you own.

National law

Forty-two states currently allow the removal of property. Eight states prohibit individual possession of silencers:

  • California
  • Delaware
  • Hawaii
  • Illinois
  • Massachusetts
  • Big Apple
  • New Jersey
  • Rhode Island

The District of Columbia has also banned the possession of suppressors.

Local Government Regulations

Some cities and counties have also enacted ordinances prohibiting or restricting the possession of suppressants in their jurisdictions. Your best bet is to contact your local police to find out if owning a silencer is legal in your town.

Best Blackout Suppressors .300 Buy

We didn’t include the suppressors in our list because, frankly, the high-level suppressors do pretty much the same thing. Let’s face it, a five decibel difference in noise reduction is not detectable without sophisticated testing equipment. Rather, it depends on the design and quality of the materials. Other factors, such as ease of maintenance and repair, are also important. It’s my pick for the best .300 blackout suppressors.

Radical firearms 7.62 Consideration of direct wire removal

If you’re on a budget, finding a decent muffler can be a challenge. Radical Firearms has risen to the challenge with its line of DC suppressors. Radical firearms are much cheaper than the other devices on my list, but they perform much better than their price.

Radical Firearms 7.62 Straight Thread Suppressor is the work of one man. I would call it utility design and manufacturing. These oppressors follow the concept of function before form. While this approach can reduce costs, it can result in a less visually appealing final product.
