After the assault weapons ban ended I treated myself to a new bushmaster M4/A2 with the new Izzy Flash Suppressor / Compensator. I originally wanted the A2 birdcage on it but was told that I could not get the birdcage on it because the barrel length would not be legal. So I get it with the Izzy suppressor on it. Well now I am seeing a ton of posts saying that the izzy suppressor sucks and that many that have fired it during low light report huge balls of flame coming out of the end of their barrels. I know mine is not the izzy brake and as soon as I can I plan on firing it during low light to see if it really does suppress the flash. I guess what my question is has anyone else had my same concerns or maybe someone out there has actually fired the izzy suppressor / compensator and can give me the details. If my concerns turn out to be true I am going to be pissed. I use the rifle on my tactical team and it must suppress flash or else what good is it.
