Looks kind of ground breaking. Albeit expensive....
Barrett BORS System
Heres the video explanation
Expensive - that's for sure!
The BORS on a Leupold - $2,700 from Barrett. That said it sure seems a very useful as well as versatile piece of gear. The demo was very impressive and even tho windage not taken in - that is a small factor for the shooter to deal with as elevation trajectory is really the key at various ranges.
