flip of a coin?

given both flash hiders aac black out vs. sei vortex which is best over all to use with/out a can[which is the best can as well?]-16’’ 308 barreled set up ?

Haven’t tried anything else but the aac bo and it works very well for my apps.

a couple of videos floating around addressing yoiur question.

mo, Splitting hairs on those two. Look @ the can compatability as well.

aac is the winner for all next is the can for it !
