Beware... Anyone on my right when I'm shooting my Mini-14!!
That rifle really kicks out the brass.
There is one range I go to that provides portable "walls" made up of PVC tube and screen netting that you can put up next to you on your bench or table to stop your flying casings.
Brass catchers are also a pretty good idea if you can find one made for your rifle.
Overall, if you know that your gun really throws out the hot brass, it would only be considerate of you as the shooter who is going to be shooting along with others on the range who could be on your right to have something prepared to set up such as a brass catcher so not to disturb your neighbor shooting on your right.
