My gun script is working when I aim, but when I try to move camera while aiming, it doesent move???

I made a gun script, and when I right click to aim, it works fine, but it wont let me move my camera while im aiming.

Script

local Gun = script.Parent.Parent.MusketTest
local AimPart = script.Parent.AimPart
local Main = script.Parent.Main

local Cam = game.Workspace.Camera

local Hum = game.Players:FindFirstChild("HumanoidRootPart")

Gun.Equipped:Connect(function(mouse)
    mouse.Button2Down:Connect(function()
        Cam.CameraSubject = Gun.AimPart
        Cam.CFrame = Gun.AimPart.CFrame * CFrame.Angles(0, 0, 0)
    end)
end)

Thank you for youre feedback!
