![]() This has all sorts of practical utility, ranging from self-defense to low light hunting, and of course military application. Either way, the end goal is the same – to minimize the amount of flash seen by the shooter when using the gun. The shorter barrel necessitated some sort of device to reduce the visual flash of a fired round in low light conditions, and the obvious solution was to simply shroud it with a metal cone.įlash hiders work by either concealing the muzzle flash (burning gases at the muzzle of the gun) or redirecting it through slots or holes in a muzzle device. ![]() These can be most famously seen on the British Enfield “ Jungle Carbine” of WWII. Some of the earliest flash hiders were little more than metal cones that clamped over the muzzle of a rifle. And if you don’t, follow along as we break it down. Now we’ll go in-depth into the function of muzzle brakes and flash hiders.Īgain, if you already know this, great! Please share this article with people who might not. We already went over the difference between a sound suppressor vs a flash suppressor, with a brief look at muzzle brakes and flash hiders and how they work. Sometimes the terminology can be confusing, and it is often made more confusing by anti-gun propaganda. You do not want to be anywhere adjacent to this muzzle brake while it's being fired.There are three common devices that are often found on the muzzles of firearms – sound suppressors (or silencers), flash hiders (or flash suppressors) and muzzle brakes. These vent laterally and to the rear, incredibly eliminating much of the recoil. ![]() For the largest cartridges.50 cal comes to mind. One thru the bore sized exit in the center of the device, and smaller blasts from each of the smaller exhaust ports surrounding the bore port, or muzzle, of the device.Īnd the Grand Daddy. So you've got two separate impulses, albeit micro-milli seconds apart. If you can visualize this, gases are metered from the muzzle device immediately outside the barrel where the muzzle device is attached, and directed thru channels to be released in a ring of porting adjacent to the muzzle. The forward (linear) venting is the most interesting, and possibly the least effective, but the easiest on other nearby shooters. Some vent vertically to keep the muzzle down, Later, we had the new improved birdcage design. I witnessed a car window explode from a muzzle device blast even though the car was a safe distance from the firing line.Įarly Vietnam era flash hiders were three prong. There are some muzzle devices that are absolutely punishing, as the blast and concussion are redirected to people and things not intended to withstand such a concussion. Here's one of many videos showing the effects of different muzzle devices.Īnd as I always say, there's no free ride. There are some combination flash hiders and muzzle brakes that do both. ![]() Some flash hiders calm the blast and recoil impulse a little, and some muzzle brakes calm the flash a little. Muzzle brakes can be very effective at reducing recoil. There are some after market flash hiders that are far more effective.Īnd muzzle brakes, they minutely change the timing of the muzzle blast, so instead of one big blast thru the muzzle, they brake up the blast to allow the blast to escape in different directions simultaneously, and/or they change the timing of the blast so it doesn't all happen at once. They may change the flash pattern, but again, very ineffectively. The standard flash hiders do a very poor job of diminishing a flash. At night time in full auto, the flash can completely obscure the target. I've shot many rounds in dark or low-light conditions. ![]()
