I am looking to buy the Vortex Viper PST 4-16x50. I am wondering if this scope will fufill all my needs. I am 19 and new to long range shooting and I want to get the right scope. I am going to be using this scope to hunt in wisconsin as well as range shooting up to 300 yards for now. I'm going to be putting this scope on an M40T4 from Tactical Rifles down in Florida. I am wondering if there is a time period when scopes go on sale or something. Everywhere I look the scope costs 700, I would like to pay a little less. Thanks for the help guys.
