Upgraded Iron Sights is a weapon attachment from Call of Duty: Black Ops. Costing just 250CP it is the cheapest attachment in the game, but it does the least. It changes the standard iron sights on some pistols to a new design with two white dots on the back posts and one on the front post.
As the change is purely cosmetic, the effectiveness of the attachment is dependant on the player. Most players find that it is only really effective when used on night maps, and in most situations, other attachments are more helpful.
