Are you Xbox one?

For starters full sentences on the forum will help us understand you easier so we can help you, but to avoid sounding completly conceited,... if you are level 7 you don't have much options in the way of fantastic gear yet. The game does a decent job of supplying you with ok gear as you progress through the story line, as for crucible idk. But your best options are to pay attention to what the gunsmith and vanguard rep are selling. They will have armor that scales with your level and if you have it, the vanguard armory over in the hangar has some good starting gear as well. Aside from that, your better choices will come from engrams. You'll also learn what kind of stats are good as you get used to the game more.
