How do I make an equip delay?

I would create a server script and put code like this:

local delay = 10

game.Players.PlayerAdded:Connect(function(plr)
    wait(delay)
    local weapon = game.ReplicatedStorage.Weapons.Weapon:Clone()
    weapon.Parent = plr.Backpack
end)

I haven't tested it, but I think it'll work fine.
