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 also makes it three times more effective against M.O.A.B class bloons. Cost: $2975 (Easy), $3500 (Medium), $3780 (Hard), $4200 (Impoppable)
