lets keep it short .
1st : "Level isnt high enough" that doesn't mean you can't rob m4/sniper . You can get weapons from robbing house or by requesting your friend to drop you a weapon by /dw that u can't
buy even if your "Level isnt high enough"
2nd: You lose all your weapons in jail and you can claim your weapons back by evidence locker but not its ammo
3rd: Your sniper crosshair is shaky because ur a god damn nerd greenhorn/new to game you can get ur sniper aim back to normal by practicing/shooting players in fights or vehicles gas
tanks
Tip : Those all are mikecops features/updates
