Allows Sniper to take multiple shots and attack 3x as fast.
~ BTD5 Description
Semi-Automatic Rifle is the 3rd upgrade of the 2nd path for the Sniper Monkey and it allows the monkey to fire three times as fast. It is most effective when combined with Point Five-Oh, popping up to 21 layers of bloons every three shots, which makes it shoots three times as fast against M.O.A.B. Class Bloons. In BTD5, it costs $2975 (Easy), $3500 (Medium), $3780 (Hard), $4200 (Impoppable).
In BTD6, this upgrade makes a return, but under the new name Semi Automatic. However, it is now no longer possible to purchase both Full Metal Jacket/Large Calibre and Night Vision Goggles at the same time. It costs $2975 on Easy, $3500 on Medium, $3780 on Hard, and $TBA on Impoppable.
