It only takes one finger - NightForce Clamp-on Power ATACR/SHV 14x/SHV 20x Rifle Scopes Throw Lever

This magnification throw ring is the best I have seen. It looks great, works great and fits the way it should. No need to struggle changing your setting ever again. One small note, tightening the device is a little odd due to the angle it is at. Starts easy, but as it recieds it hard to set the wrench at the proper angle. Still only took a couple of minutes. Will be buying these for all of my scopes.
Only The Truth.
