Depending on your shooting style or rifle configuration, to take your firearm to the maximum level of performance you demand, you may need to get a scope riser. Scope risers are designed for a variety of applications, but they primarily help you to shoot from a more natural position hence alleviating neck strain and allowing you to aim more comfortably for longer periods of time. An may also have a secondary purpose as some assault rifles have a high FSB (front sight base) that may blur a section of your scope, but a scope riser will effectively raise your scope so such a conflict is no longer an issue. AR scope risers also come Picatinny rail ready, and they are easily installed or removed depending on how you want to deploy your rifle that day.
