There are three main types of muzzle devices for your weapon: flash suppressors/flash hiders, muzzle brakes, and compensators. AR-15â€™s are getting more and more popular every day, partially due to their low recoil and muzzle rise. But with a good muzzle brake, recoil can be reduced even more. With a good compensator, muzzle rise significantly drops, almost vanishing. And while muzzle flash cannot be completely eliminated, it can be significantly reduced with a quality flash hider. These muzzle devices are growing increasingly more popular due to how easy they are to put on, 5-10 minutes with the right tool, because of their incredible efficiency, and because they make a cool-looking gun.
