Camera and viewmodel floats up instead of getting on right position

[Mihaqwest5 (EverlastingWinter)]

Whenever i try launch a game and set current camera CFrame it’s just floats up or bouncing against the ground

1. What do i want to achieve? I need to fix the issue related to SetPrimeryPartCFrame on viewmodel

2. What’s going on with the camera?
   

   
   
   
   

3. What solutions have i tried so far?: I tried anchoring/unanchoring, changing colision and etc.

There is examples of scripts and then viewmodel in explorer picture.
MODULE SCRIPT

local GunScript = {}
local RunService = game:GetService("RunService")
function GunScript:GetTool(Which, ToWhichChar)
	local ToolObj = Instance.new("StringValue")
	ToolObj.Name = game:GetService("ReplicatedStorage").GunStorage:FindFirstChild(Which).Name
	ToolObj.Value = game:GetService("ReplicatedStorage").GunStorage:FindFirstChild(Which).Name
	ToolObj.Parent = ToWhichChar
end
function GunScript:EquipTool(Which)
	return coroutine.create(function()
		local plr = game.Players.LocalPlayer
		local plrcam = workspace.CurrentCamera
		local char = plr.Character or plr.CharacterAdded:Wait()
		if char:FindFirstChild(Which) then
			local Rightweapon = game:GetService("ReplicatedStorage").GunStorage:FindFirstChild(Which):Clone()
			if Rightweapon then
				Rightweapon.Parent = plr.Character or plr.CharacterAdded:Wait()
				RunService.RenderStepped:Connect(function()
					if Rightweapon.PrimaryPart then
						Rightweapon:SetPrimaryPartCFrame(plrcam.CFrame)
					end
				end)
			end
		else
			warn(plr.." Doesn't have a called weapon!")
		end
	end)
end
return GunScript

LOCAL SCRIPT

local Players = game:GetService("Players")
local CurrentGun = nil
local Holding = false
local GunScript = require(game:GetService("ReplicatedStorage").GunSystem:WaitForChild("GunScript"))
local plr = game.Players.LocalPlayer
local UIP = game:GetService("UserInputService")
local TS = game:GetService("TweenService")
local function UnEquipWeapon(Which)
	local char = plr.Character or plr.CharacterAdded:Wait()
	char:FindFirstChild(Which):Destroy()
end
UIP.InputBegan:Connect(function(InputObject, gameProcessedEvent)
	if gameProcessedEvent then return end
	if InputObject.KeyCode == Enum.KeyCode.One then
		if Holding == false then
			Holding = true
			CurrentGun = GunScript:EquipTool("SMG")
			coroutine.resume(CurrentGun)
		else
			Holding = false
			coroutine.close(CurrentGun)
			UnEquipWeapon("SMG")
		end
	end
end)

VIEWMODEL IN EXPLORER

Thank to anyone who will help me!
P.S. Module script Setup is just a parameters.
