Muzzle devices like Aero Precision’s classic A2 flash hider will help protect you from becoming blinded should you ever find yourself firing your rifle in a tactical situation at night. The Aero Precision A2 Birdcage Flash Hider is designed to fit 5.56/.223 caliber barrels with ½-28 TPI (Threads Per Inch). It’s made in the United States of America and will give your rifle a great finishing touch.


Flash hiders—also called flash eliminators, flash guards, flash cones, and flash suppressors—reduce the visible flash caused by gases exiting a rifle’s barrel at high speeds. A flash hider like the one offered by Aero Precision works by cooling and/or dispersing the burning gases, protecting you from being blinded by your own gun in low-light shooting conditions. The primary purpose of the Aero Precision Birdcage Flash Hider is to benefit you, but it can also be utilized to prevent an enemy from seeing your firearm’s visible flash.

Flash Hiders vs. Muzzle Brakes

Flash hiders like the A2 flash hider from Aero Precision aren’t the same thing as muzzle brakes, even though some muzzle brakes also double as flash hiders. Unlike flash hiders, the primary purpose of muzzle brakes is to reduce recoil in firearms that use large caliber cartridges.

Flash Signatures and Modern Rifles

The problems associated with visible firing signatures became apparent with the advent of the modern rifle with a shortened barrel. When a bullet is fired from a long barrel, most of its powder is burned out before it exits. But with a shorter barrel, the powder from a bullet has less space to burn before blowing out of the muzzle, and the end result is often a blinding pyrotechnic-strength flash that can blind you if you’re not careful when shooting your rifle at night. A flash hider will work to redirect the flash to the side away from your line of sight so that you can preserve your night vision.

Nighttime Operations

Anyone who engages in nighttime operations with a rifle should be aware that no flash hider can eliminate flash signature completely. You will still need to adjust your position after firing your gun to prevent an enemy from zeroing in on you. But using an A2 flash hider like the Aero Precision Flash Hider can help you greatly, especially since it doesn’t have any prongs on the end of it like other flash hiders. It’ll make it more user-friendly and less likely to get caught on clothing, vegetation, etc. when moving around with it on your rifle.
