I see a people on here was made this, but it doesn't perfect. So I made this.

Please note: not to confused with Alex Wollas version, which it have a different scope and holding position. While this models I port from Left 4 Dead 2 with original scope and custom holding position.

Replace Level Action or Sniper Rifle in 2 slot, including weapon data for both slot (not HUD icon).
You are not allowed to port and modify my mods for mobile version.
