Welcome to the Weatherby Nation Krakka! You will also receive a thread protector with your Accubrake. You may or may not have used brakes on other rifles in the past, but JIC, a word of caution. Always use hearing protection on the bench(let the people around you know you are using a brake so they can be ready) and in the field. In the field, a pair of corded ear plugs hung around your neck and inserted at the time of the shot will protect against hearing loss. Many people don't like to wear them in the field, but if you shoot from a deer house or you happen to shoot into the wind, you will definitely feel the pressure of the blast, and the blast is deafening leaving a ringing in your ears (tinnitus) for days, weeks, and sometimes a lifetime. Like the commercials say,"Protect It or Lose It." Theres a lot of different types of hearing protection available and there are different opinions about all of them,("everyone" tells you which one they like)but use some form of hearing protection, or you'll regret it later on in life, and sometimes immediately. Excuse my spouting off, as you likely are aware of all the pitfalls and advantages of using brakes, just trying to give a little support to enjoying your new rifle. Good Luck, and again, Welcome.
