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)
