There is no definitive answer to this question as it depends on the brake itself.
A muzzle brake is a simple device to install, and it just needs a few tools to do so correctly. But it needs to be securely tightened against the barrel in order to ensure accuracy and safety. If it is not properly tightened, it can loosen over time and cause the barrel to move, which would affect the firearm’s accuracy.
There are many different types of tools that can be used for this purpose, such as wrenches, torque keys, and even pliers. It’s important to use the proper tool for your specific firearm in order to avoid any damage that might be caused by using an inappropriate tool.
While working on your gun, it might be helpful to have a vise or some other type of rest to keep it steady. A two-inch or three-inch adjustable wrench will be the main tool you’ll use for this job. It is also helpful if you’ve got a torque wrench.
Depending on the brake you choose, you may need a crush washer, peel washer, or jam nut for installation. Many brakes come with these items if they are required.
