M14 Flash Suppressor vs 308 A2 birdcage

[Sailormilan2]

Of the two, which is a more effective Flash Suppressor? The longer M14 style, or the shorter A2 extended birdcage style?

I would suggest asking over at , the M1A / M14 is the firearm of choice over there.

Unless the added length was just for the bayonet mounting...

FWIW, the FAL used one just as long.
