The Camera's XYZ axis aren't updating as expected?

Please help!

When I'm crouched, the recoil for the camera is weird. it's difficult to explain, so watch this video to get an idea of whats happening. To get the Camera's XYZ offset to update fluidly I just use runService, though it doesn't seem to be working as smoothly.

Here's my code:

-- Shoot --
function OffsetAxis()
	x2 = Character.Humanoid.CameraOffset.X
	y2 = Character.Humanoid.CameraOffset.Y
	z2 = Character.Humanoid.CameraOffset.Z
end

-- Sets Model to Camera CFrame --
RunService.RenderStepped:Connect(function()
	viewModel:SetPrimaryPartCFrame(Camera.CFrame * CFrame.new(-0.1,-1.5,0.5))
	renderloop()
	OffsetAxis()
end)

local OffsetP = {CameraOffset = Vector3.new(x2,y2 + 0.08,z2 - 0.04)}
local Infor = TweenInfo.new(0.1, Enum.EasingStyle.Circular, Enum.EasingDirection.In)
local OffSetd = game:GetService("TweenService"):Create(Character.Humanoid, Infor, OffsetP)
local x = viewModel.Classic.Bottom.Top.C0.X
local y = viewModel.Classic.Bottom.Top.C0.Y
local z = viewModel.Classic.Bottom.Top.C0.Z
local Properties = {C0 = CFrame.new(0.5,y,z)}
local Info = TweenInfo.new(0.1, Enum.EasingStyle.Quint, Enum.EasingDirection.InOut)
local Back = game:GetService("TweenService"):Create(viewModel.Classic.Bottom.Top, Info, Properties)
local lol = {CameraOffset = Vector3.new(x2,y2 - 0.08,z2 + 0.04)}
local ll = TweenInfo.new(0.1, Enum.EasingStyle.Circular, Enum.EasingDirection.Out)
local Anim = game:GetService("TweenService"):Create(Character.Humanoid, ll, lol)
local Properties2 = {C0 = CFrame.new(x,y,z)}
local Info2 = TweenInfo.new(0.1, Enum.EasingStyle.Quint, Enum.EasingDirection.InOut)
local Forward = game:GetService("TweenService"):Create(viewModel.Classic.Bottom.Top, Info2, Properties2)

Mouse.Button1Down:Connect(function()
	if CanShoot == true and shooting == false then
		if not Forward.Completed then
			Forward:Stop()
		end
		shooting = true
		OffSetd:Play()
		CanShoot = false
		Vandal.Fire:Play()
		Back:Play()
		wait(0.1)
		Anim:Play()
		Forward:Play()
		wait(firerate)
		CanShoot = true
		shooting = false
	end
end)

-- Crouch --

local anim = script.Crouch
local play = Character:WaitForChild("Humanoid"):LoadAnimation(anim)

UIS.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.LeftControl then
		IsCrouched = true
		Character.Humanoid.WalkSpeed = 8
		local Properties = {CameraOffset = Vector3.new(x2,y2 - 0.5,z2)}
		local Info = TweenInfo.new(0.2, Enum.EasingStyle.Quint, Enum.EasingDirection.InOut)
		local T = game:GetService("TweenService"):Create(Character.Humanoid, Info, Properties)
		T:Play()
		play:Play()
	end
end)
UIS.InputEnded:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.LeftControl then
		IsCrouched = false
		Character.Humanoid.WalkSpeed = 12
		local Properties = {CameraOffset = Vector3.new(x2,y2 + 0.5,z2)}
		local Info = TweenInfo.new(0.2, Enum.EasingStyle.Quint, Enum.EasingDirection.InOut)
		local T = game:GetService("TweenService"):Create(Character.Humanoid, Info, Properties)
		T:Play()
		play:Stop()
	end
end)
