So still learning as I am getting into long range shooting. Just bought my Savage Stealth in 308. What are the advantages and disadvantages of having a muzzle brake on your rifle. What exactly is it's job? It seems that they are louder with them on than not having one on. Is this the case? Also, whats the difference exactly between a $100-150 muzzle brake and a muzzle brake you buy on Ebay for $30. Just trying to understand the whole thing on what exactly a muzzle brake is for and if I really need to put one on my rifle. Thanks for your help and time.
