How do I make the FE Gun kit damage cancollide false objects?

So I've been wondering, I have this gun kit set up already, and I want it to shoot through cancollide false objects for example; armour. Basically, the bullet registers armour as an object, which it is but I want it to be a part so like if the player shoots one of the armour pieces, the player wearing the armour gets damaged. I've looked through EVERY single script of this gun kit but can't find a result on how to do this. Here's a damagemodule in serverscriptservice, (may not be enough).

local module = {}

module.CanDamage = function(obj, player)
    if obj:FindFirstChild("Humanoid") then
        local p = game.Players:GetPlayerFromCharacter(obj)
        local creator = obj:FindFirstChild("Creator")
        if creator then
            p = creator.Value
        end
        if p then
            if p == player then
                return false
            else
                if p.Neutral or player.Neutral then
                    return true
                elseif p.TeamColor ~= player.TeamColor then
                    return true
                end
            end
        else
            return true
        end
    end
    return false
end

return module
