i my opinion the nex should be wall-penetrating, able to do (powerful) headshots, do high damage even with a normal hit, have a high reload time and zoom as secondary.
the rifle should be less powerful, should NOT be wall-penetrating and headshots should NOT do extra damage. the reload time should be lower, and the secondary could be something else.
the reason for this is that the nex should be one of the most powerful weapons. therefore all the "features" (wall-penetrating, headshot), but no secondary as the primary should be reason enough to use it (as the rocketlauncher, it's also powerful and it's secondary is also not really a firemode). the camping rifle is just a rifle. it fires the same bullets as the mg does. therefore it shouldnt be so powerful, and may have a secondary.
the camping rifle would just be another weapon placed like any other weapon. the nex would be a special weapon placed in hidden or hard-to-reach places.
