How would I make a Gun / Armament not intersect in walls / floors?

I have created a code that sets the pivot to the CurrentCamera in Lua. I’m also considering implementing a raycast: if the raycast detects a collision, then the viewmodel will be pushed back.

camera_manipulation.viewmodel_Tocamera = function(viewmodel)
	local firePart = viewmodel:FindFirstChild("Nodes", true).FirePart
	local filterparams = RaycastParams.new()
	filterparams.FilterDescendantsInstances = {currentCamera, viewmodel, player.Character}
	filterparams.FilterType = Enum.RaycastFilterType.Exclude

	viewModelToCamera = runService.RenderStepped:Connect(function()
		local part = Instance.new("Part",workspace)
		part.Anchored = true
		part.CanCollide = false
		part.CFrame = firePart.Parent.Parent.PrimaryPart.CFrame
		part.Size = firePart.Size
		part.Transparency = 1
		local rayResult = workspace:Raycast(part.Position,part.CFrame.LookVector * 5 , filterparams)
		if rayResult then
			print(rayResult.Instance.Name)
			viewmodel:PivotTo(currentCamera.CFrame * CFrame.new(0,0,rayResult.Distance))
		else
			print("Not hitting anything")
			viewmodel:PivotTo(currentCamera.CFrame)
		end
		part:Destroy()
	end)
end
