Above is the USGI Birdcage.

Above is the Vortex®

Vortex® with teh US Army.

A commando (11.5" barrel) M16 is shown firing a burst of 10 rounds of M855 ammunition each,. one with the standard USGI birdcage flash hider and the other equipped with the Vortex® flash hider. The idfference is amazing. If I had not been there, I would not have believed it.

Another great product is the Smith Enterprise muzzle break for the M14. This controls muzzle rise during firing. When fitted to a select fire rifle, the muzle rise is negligable. For a short video showing the effectiveness of the Smith Enterprise muzzle break, click here. (56K beware)

Here is the new prototype Vortex® flash hider for the General Dynamics M2HB Enhanced machine gun. It is shown next to a 7.62mm vortex. You can also see links o' fun on the table. Scroll down so see some very interesting images of the test. You can also see videos of the test, both M2HB without the Vortex® attached and M2HB with the Vortex® attached.

Here is the test set up.
