| Just installed one, How EXACTLY does this simple device work? I gooooogled this with no luck, links or pics would help. |

What type do you have and what is it installed on? A generic flash hider is designed to hide the muzzle flash. It does this by dispersing the muzzle's hot gas and still burning propellant into smaller segments reducing or eliminating the perceived "flash." Mike I just know my Vortex works great at eliminating the flash from my SBRs. |
| As mentioned....channels the hot/bright exhaust gas into a smaller area....basically keeps the SHOOTER from seeing a bright ball of light in front of him as he shoots...allows keeping his eye on the target better. Isn't going to "hide" the flash from the target area. |
that was the reason they were banned in NY lol. try to explain that to people and they look at you. Question: Why do you need one of those on a gun? Answer: So when I fire 600 rounds I dont go blind. Them:

Not that I am aware of, if they had them I am sure The Army would of given me one to carry. We did however use air support and no one knew where the shots came from

Some are better than others. I only have A2 flash hiders on my rifles, but as was posted the vortex is supposed to all but eliminate flash. Also the type of powder makes a big difference. Most of my .223 reloads use win 748 that gives allmost no flash from a 20" rifle without a flash hider. |

There is a difference between a flash hider, and a flash suppressor. A flash hider is just usually a crude conical device that contains the flash a bit while hiden from the shooter. The flash still happens, but it's more contained and somewhat blocked from the shooters view. In practice, this will also yield a little flash suppression. See what's on the end of a Lee Enfield #5 Jungle Carbine. A flash suppressor actually attempts to reduce the flash. Some are much better than others. It's all about how the blast which contains still burning hot gasses is released into an oxygen rich atmosphere. No suppressor is the worst case because at a instant, extremely hot still burnining gasses are dumped into the asmosphere at an instant where it reacts with the oxygen and burns itself up. The amount of heat, pressure, left over powder and oxygen available are what maximizes the flash. A suppressor attemps to time the release of these gasses so that the pressure and temperature have dropped to the point where they will no longer have the physical properties to react with the atmosphere with a flash of light. A longer barrel will have less of a capacity to flash because more fuel is burned by the time the bullet leaves the barrel. A short barrel with a rifle cartridge will eject a lot of unburned propellent yeilding a huge flash. Thus, a flash suppressor designed to work with a specific load in a 20 inch barrel, will do a terrible job on a 11.5 inch barrel. The capacity of the suppressor would just be overwhelmed. |
