The Laser Sight is an attachment that will be featured in the game Grand Theft Auto V. It is a laser attached to the gun that points where the bullet will hit.
GTA III Era
The Laser Sight is only seen when looking through the scope of the PSG-1 and the Dragunov Sniper Rifle. It can only be seen when pointing the scope at a wall and since the player is looking through the scope where the Laser Sight is supposed to be it is useless in game.
GTA V Era
The Laser Sight can be seen attached to Assault Rifles in Trailers or screenshots. The colour of the sight is red. When the player gets a high wanted level the LSPD will fire Assault Rifle or Sniper Rifle with Laser Sights from helicopters.
