Oh wow I honestly thought that 3 round burst sniper was the easiest sniper to get gold lol really though the hardest thing is the brecci and the haymaker because you need headshots for them. The easiest thing by far are the lmgs. I get like 15-20 headshots per match with them. Bro if you have the time just go for it lol you'll definitely stick out in the lobby when you get it
