Sounds slightly less of a high pitched crack and more of a pop pop and all sound is directed towards the target. My ffl gunshop owner has one on his ar and I wanted one for the " cool" factor. It's definitely different. Can't comment on its flash suppressing ability since I rarely pay attention to that. It took a month to come in. I had to order a large pin to small pin adapter and threw this on the order along w a vltor stock as well
Of course they reduce flash too so check local laws and ordinances too. Keep records of anything you buy.
You can find someone that can paint you a belching pig or a skull, etc.. a lot cheaper than the above.
