(Disclaimer, you need portal for this. Not portal 2, but just portal 1. i can't belive i have to say this.)

this is a map from gmod.org that works suprisingly well. this is essetially a target range using props and textures from portal. It also contains some ammo dispensers for pistol,smg,pulse/ar2,and rpg ammo. dont cry to me that everything is missing textures because that means you dont have portal mounted. Please be aware this requires no addons, so that means that it is not meant for the portal gun addons, but you can use them at your risk, one last thing, if you have lighting issues like weapons being bright, go to your advanced video settings and change the high dynamic range to none. this will not only fix the issues, but it will allow the game to run faster.
