I was watching a video and the shooter had a elevation guide that was attached to his scope. It pulled out like a retractable tape and had his elevation settings marked on it for different yardage. Does anyone know where I can buy one of these or what they are called?

Surely someone knows what I am trying to describe here. The tape looked like it unrolled from the top turret.

I think midwayusa.com has this. It is popular with tactical shooter's some. You might also check www.riflescopes.com.

Thanks, I'll check them out. Does anyone know the proper name for this accessory?
