How do I make it so if you join a group they recieve a special weapon from ReplicatedStorage?

So how would I make it that if someone joined my group and then I have a weapon in ReplicatedStorage. If they join the group and join my game they will receive the item and also please make it so when they die they respawn and receive the weapon again. I want the item to be specific in this case the RPG i have in replicated storage.
