After unequipping tool, script.Parent.Activated:Connect executes twice?

WARNING: VERY CRAPPY CODE!

Whenever I unequip my gun (not dropping) and re-equip, it works normally except for

script.Parent.Activated:Connect(function() @ (Line 81)

The line executes multiple times for a reason I cant explain. Here is my local script:

-- Preference Locals
local MaxAmmo = 1
local ShootDelay = 0.2
local MaxCamShake = 1
local ReloadTime = 7.5
-- Main Locals
local Unequipped = false
local Ammo = MaxAmmo
local Reloading = false
local MuzzleOn = false
local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:wait()
local humanoid = char:WaitForChild("Humanoid")
local Mouse = game.Players.LocalPlayer:GetMouse()
local camera = workspace.CurrentCamera
local counter = 0


--Animation Locals
local AnimationStatus = "Off"
local animationOn = script.Parent:WaitForChild('On')
local On = humanoid:LoadAnimation(animationOn)

--Main Stuff lol
--I suck at coding but ill optimize this crap latrrrr
--here i am procrastinating by adding useless green text thats probably gonna be removesd later
local function nowits6rlly()
    if AnimationStatus == "On" then
        On:Play()
        On.Looped = true
    elseif AnimationStatus == "Off" then
        On:Stop()
        On.Looped = false
    end
end

local function CreateMotor6D()
    local PlayerGunConnect = Instance.new("Motor6D")
    PlayerGunConnect.Part0 = player.Character:WaitForChild("Right Arm")
    PlayerGunConnect.Part1 = script.Parent.MainAssembly
    PlayerGunConnect.C0 = CFrame.new(0,-3.5,-0.63)
    PlayerGunConnect.C1 = CFrame.Angles(math.rad(90), 0, math.rad(180))
    PlayerGunConnect.Parent = script.Parent.Motor6D
end

local function DestroyMotor6D()
    local test = script.Parent.Motor6D:FindFirstChild("Motor6D")
    if test then
        script.Parent.Motor6D.Motor6D:Destroy()
    end
end

local function CamShake()
    for i = 1,10 do
        wait(0.025)
        char.Humanoid.CameraOffset = Vector3.new(math.random(-MaxCamShake,MaxCamShake), math.random(-MaxCamShake,MaxCamShake), math.random(-MaxCamShake,MaxCamShake))
    end
    char.Humanoid.CameraOffset = Vector3.new(0,0,0)
