Matthew Stafford is waaaay better that Aaron Ro.... I'm sorry I tried to type that with a straight face

You test common weapons each week for the gunsmith. This allows you to buy weapons and get them on armsday, which is every Wednesday. After purchasing a package from the gunsmith you wait until the next Wednesday and you can go to him and he will give you your weapon from a package. Note: If you buy a package on Wednesday you have to wait another week. Every rank you get a random weapon on spot after ranking up. At rank 2 he gives a quest for a class-specific legendary weapon. Titan: Immobious, Warlock: Susanoo, and Hunter: Stillpiercer. When you hit rank 3 he gives a quest for a class-specific exotic. Titan: Fabian Strategy, Warlock, Tloac, Hunter: Ace of Spades. At rank 5 you get a quest for the First Curse exotic.

Each rank with the gunsmith, up to rank 3, get you a differnt perk roll with each gun you order. Maximum amount of guns you can order at a time is dependent on rank. Each wensday you will get your weapon from the previous week (order one today, receive your weapon next week). If you have diffculty choosing a gun for your play style, I highly suggest you go on youtube and go to Planet Destiny's youtube because they go over each perk roll for each order every week to see which one suits a pve or pvp player.

With rank 1 you get to obtain 1 weapon from armsday, with I think the choice of only 1 weapon roll. Rank 2 lets you get 2 weapons with 2 choices of there roll. Rank 3 from what I can tell lets you obtain all 5 weapons and 3 different roll choices. (Lets me get all 5 guns on all characters when two of them are rank 3 and one is rank 6.)
