Issue with lerping

Help and Feedback Scripting Support
#1

I’m making a gun system and I need the gun to transition towards the camera to aim down sights. The issue is that the gun kind of falls downwards (since the entire gun is unanchored)

If I anchor the gun, then it won’t be able to play animations.

run.RenderStepped:Connect(function()
	if uis:IsMouseButtonPressed(Enum.UserInputType.MouseButton2) then
		gun.PrimaryPart = gunModel:WaitForChild("AimPart")
		gun.Parent = cam
		
		for i = 0, 1, 0.05 do
			gun.PrimaryPart.CFrame = gun.PrimaryPart.CFrame:Lerp(cam.CFrame, i)
			task.wait()
		end
	else
		-- code here runs when player isn't aiming down sights
	end
end)

The code works as intended, just the gun is falling downwards when trying to aim down sights and I don’t know how to fix this without anchoring the gun

Try using attachments or lock the gun’s position

how would i use attachments in my situation and how do i lock the gun’s position? if i lock the gun’s position, can it still be animated?
