at the range you are assigned a port next to someone with a loud ass muzzle braked rifle? The whole range was full so I got a port next to this dude with an ar-15... that .223 blast was redirected right in my face. Plus his retarded cardboard "shield" he put up did crap.. all his casings flew over and hit me in the head too. I mean normaly I don't mind but it really ruined my shooting experience until he left. oh and don't say I'm being a girlie man either, the range officer next to me was complaining too.
