very profession and industry has their own specific language. From acronyms that get pronounced like words to phrases you’d never heard anywhere else, they’ve all got a form of communication that only those who are “in-the-know” will know. The firearms industry is no different. Even if you’re brand new to the gun world and its specific terms, it’s highly likely you’ve encountered one, two, or even all three of these terms: muzzle brake, compensator, and flash hider (sometimes called a flash suppressor)—but it can be easy to get confused as to what is what, especially if you throw in the legal interpretation of these terms in various states, just for some extra confusion. For the newcomers: this piece will teach you about the three terms, their corresponding muzzle devices, and their different purposes. For the experienced shooters: it’s OK to read this article. I won’t tell anyone you’re brushing up on your knowledge base.
