Ok, I removed my A2 style flash hider today in order to install a new one from LaRue Tactical. When I removed the old one, I found a lot of build up on the barrel end. Is this normal? Was I correct to scrape all of this off before I installed the new one, and what causes this? Was the first one not installed correctly? Just a few questions I wanted to throw out there.

No, not if your barrel is threaded. It is a simple matter of unthreading the old one and threading on the new one. But , like my new one, I had to use a peel washer and slice off quite a bit of it, in order to get the new comp. to line up correctly.
