I've searched and read a few reviews of the NEA Crusader muzzle brake, mostly about its performance. Just wondering if anyone has any experience standing beside one firing .223/5.56? 
I picked one up for my AR build and didn't really think much about it at the time, but I will be shooting indoors quite a bit, so wondering how loud it is to the sides?
Also, what is up with the finish on them? Looks a little rough.
