    Why the preference for the Vortex over the AK74 type pictured here
    Your picture shows an AK74-type muzzle brake.

    A flash suppressor is intended to reduce the visibility of muzzle flash (from the perspective of the shooter) to preserve night vision. The flash is still quite visible from the perspective of the target. Flash suppressors work by rapidly expanding and cooling propellant gases as they leave the end of the barrel. The density and temperature of any remaining burning powder are greatly reduced along with the brightness of the flash. Flash suppressors may have some positive effect on muzzle climb, but that is not their primary purpose.

    Muzzle brakes or compensators, on the other hand, are intended to reduce recoil and muzzle rise during rapid fire by redirecting propellant gases. Escaping gas creates four effects: noise, pressure, blast, and flash. Noise increase is necessary to most designs because higher velocity gases impart more energy to counteract recoil. Higher velocity produces greater noise. Pressure is felt as a shock wave similar to that made by an explosion. The blast is the physical movement of air. This has the effect of blowing up dust and debris from below and to the sides of the brake. Finally, flash is generally increased as the high pressure gasses mix slowly with surrounding air, staying hot enough to glow for a longer period of time.

    Two different tools for two different purposes.

    Here's a nice video of a flash suppressor in action:

    Elmer,
    Thanks for the clarification. For some strange reason I assumed that if you screwed something on the end of the muzzle it would perform both the functions of the muzzle compensator and the flash suppressor.

    Several years ago, when at a patrol rifle class taught by Gabe in California, we stood downrange after dark and watched the difference in flash from several muzzle configurations on otherwise similar AR rifles.

    The Vortex flash was almost invisible, the A2 birdcage flash was quite small. The bare muzzle flash was like a camera's flashbulb, and the Bushmaster AK style muzzlebrake's flash was like fireworks with sparks shooting out.

    It was definitely a "flash enhancer".

    Interesting. What do you think of this tritium rear sight for the AK?

    Maybe pair that rear sight up with an XS front sight?

    After using tritium/fiber optic sights on my Glock, I am completely sold on them. A fairly thorough internet search showed they are not available for the AK47. TruGlo says they will be making them for the AR15 next winter but has no plans for the AK. I think that XS front sights and tritium in the rear are the best solution currently available.

    Not so. Tritium night sights are available for AKs. I posted this at the beginning of this thread. Here it is again. Three dot, front and rear configurations available with the rear adjustable for windage.

    Cheers!

    Gentlemen,

    A couple of points occur to me...

    1) As a practical matter, a tritium front sight like the one linked to by AKGunny may be all you need for normal night time combat. Use the rifle like a shotgun with a bead.

    2) To a person whose eyes are fully night adjusted, tritium sights are very bright. They will partially spoil your night vision. Further, if the enemy sees them....you might as well have been smoking a cigarette.

    Try this, wake up in the middle of the night in a totally dark room, I'll bet you can read newsprint by the light from the tritium sights on your pistol, I can.
