In order to reduce that recoil, those gases need to be redirected – and that’s exactly what a muzzle brake is for. And if we recall Newton’s Third Law of Motion, that means the same energy is exerted in the opposite direction, resulting in what we feel as recoil. When you fire a gun, the energy created by expanding gases is used to propel the bullet forward. If you’re shooting a carbine or short-barreled rifle, often shoot at night, or frequently use cartridges that either require large powder charges or the use of slower-burning powder, a flash hider is going to be your best friend. But how does it actually work? The answer is that the holes or gaps in the flash hider divert the super-heated gases from the primary flash, while also minimizing oxygen flow and rapidly cooling the residual gases to reduce or eliminate the secondary fireball effect. One of the earliest examples of a flash hider can be seen with the clamp-on conical flash suppressors used on Lee-Enfield Jungle Carbines in the later years of World War II, but the example that most shooters are probably familiar with is the A2 “bird cage” flash hider that comes standard on most AR-pattern rifles. This created an obvious problem as militaries around the world began shifting towards shorter, more maneuverable carbines – while increased muzzle flash also made the shooter a more visible target, the bigger problem was that it significantly impacted the shooter’s vision during night-time engagements, and in extreme cases could even cause temporary blindness. But with a shorter barrel, where there isn’t enough time for the powder to be fully consumed, the result is an almost instantaneous two-stage muzzle flash – the primary flash is caused by super-heated propellant gases trailing behind the bullet, and the secondary flash is caused by residual gases that ignite after being exposed to oxygen in the air, creating the infamous “fireball” that you’ve probably encountered if you’ve ever fired an SBR or shot a firearm without a flash hider (especially at night). When a bullet is fired from a typical long-barreled rifle, most of the propellant is burned before the bullet exits the barrel. While the name is fairly self-explanatory, the science behind flash hiders (also known as flash suppressors) is more complicated than you might think. Have you ever wondered how a flash hider actually works, or what’s inside a suppressor? Confused about the difference between a brake and a compensator? Or maybe you’re just curious which muzzle device will help you shave a second or two off of your competition time – whatever the case may be, you’re in luck, because we’re doing a deep dive on the different types of muzzle devices and exploring the pros and cons of each one.
