Best .308 Muzzle Brake: Reviews and Guide

Before getting to the list of the best 308 muzzle brake, let's take a brief look at its formation.

Muzzle brakes are an underrated part of your gun. While some people may not quite understand them, they are extremely important, and can vastly improve your shooting performance and experience. A quality muzzle brake can be the difference between an hour of unenjoyable shooting and a fun full day at the range.

The way a muzzle brake functions is by redirecting the gas of the gun. When you fire the gun, gas is generated as the powder of the cartridge undergoes chemical reactions. When the gas exits the gun through the barrel, it creates recoil.

Let's see how muzzle brake works:

A high quality muzzle brake will channel this gas in a specific way that can greatly reduce recoil.

The secondary effects of this recoil reduction can be huge. It becomes much easier to reacquire your target, which allows you to fire a much more accurate second shot, if necessary. The reduced recoil also just makes you a more accurate shooter in general. With the amount of recoil felt reduced, you will find that it is more enjoyable to shoot.

For these reasons, muzzle brakes are important in all types of shooting. For target and competitive shooting, you will be more accurate. For home defense and hunting, your second shot will be on target faster. For plinking, you will feel less recoil and enjoy yourself more.

However, picking a muzzle brake can be pretty difficult, as there are many options to choose from. This guide is here to help.

We have chosen the best .308 muzzle brakes and reviewed them in terms of quality, price, and features. In doing so, we will help to identify the most important features to keep in mind while shopping for a muzzle brake.

We hope this guide is helpful! Let’s take a look at the best .308 muzzle brakes.

The cons of this .308 muzzle brake are the price. Despite the high quality and decent performance, many people will have a hard time paying more for a brake that doesn’t reduce the recoil as much.

However, the muzzle brake does weigh around 5.5 ounces.

The pros of this .308 muzzle brake are the performance and the durability. You can expect this muzzle brake to reduce the recoil by around 56%. It accomplishes this by venting the gases to the sides, which is where the shape comes into play. While it may not be the most aesthetically pleasing, it does help in the performance department.
