Changing part position not changing properly

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I am making a gun system and I have a module that returns the vector3 of where the barrel is pointing when I make a part that goes to that position every frame it shakes and flings all over the place but when I shoot the bullets go where they are supposed to

  2. What is the issue? Include screenshots / videos if possible!
    The end of the laser is where the part is (Where the beam is pointing)

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I have tried making it a model and using PivotTo, Using CFrames, and that’s it

ALSO! after about 1 minute of the part just flinging it starts working properly and positioning properly
if you want to code I can send it.

Send me the code,codes are critical(must send the code to us when you post a report

I don’t understand exactly what you’re trying to achieve here. Can you describe it more clearer?

Laser Handler Function

function ManageLaser(Tool:Tool)
	Tool = CurrentVM:WaitForChild(Tool.Name,5)
	local Han = Tool:FindFirstChild("Handle")
	local E = Instance.new("Attachment")
	E.Parent = Han:FindFirstChild("LP")
	
	print("DoingLaser")
	
	if LaserLoop then
		LaserLoop:Disconnect()
	end
	
	local Laserenabled = true
	
	LaserPart = game.ReplicatedStorage.Laser:Clone()
	
	LaserPart:PivotTo(workspace.CurrentCamera.CFrame)
	
	mouse.KeyDown:Connect(function(Key) 
		if Key == "t" then
			Laserenabled = not Laserenabled
		end
	end)
	
	
	LaserLoop = game:GetService("RunService").RenderStepped:Connect(function()
		if Laserenabled then
			
			LaserPart.Parent = workspace.CurrentCamera
			LaserPart.Laser.Beam.Attachment0 = E
			local pos = BulletPositioner.Get(CurrentVM,CurrentVM:FindFirstChildWhichIsA("Tool"):FindFirstChild("Handle"):FindFirstChild("ShootPos"),{game.Players.LocalPlayer.Character,CurrentVM})
			if pos then
				LaserPart.Laser.Position = pos
			end
		else
			LaserPart.Parent = game.ReplicatedStorage
		end
	end)
end

BulletPositioner Module

local module = {}

function module.Get(Character, Part)
	local workspace = game:GetService("Workspace")

	local partLookVector = Part.CFrame.LookVector
	local startPosition = Part.Position

	local maxDistance = 1000

	local raycastParams = RaycastParams.new()
	raycastParams.IgnoreWater = true
	raycastParams.FilterType = Enum.RaycastFilterType.Exclude
	raycastParams.FilterDescendantsInstances = {workspace.CurrentCamera,Part,game.Players.LocalPlayer.Character}

	local result = workspace:Raycast(startPosition, partLookVector * maxDistance, raycastParams)

	local endPosition
	if result then
		endPosition = result.Position
	else
		endPosition = startPosition + (partLookVector * maxDistance)
	end

	return endPosition
end

return module
