Re: Leupold Retractable Ballistic Chart for 30mm Rifle
I put one on my work rifle - I've used it some, but honestly kinda forgot it's there. I put a shortened more basic info list on it compared to the range card. It works fine for a rapid deployment "grab your rifle only and go" when you may not have your other info/data logs/etc.
It's made of plastic with a metal tape coiled inside - won't withstand the next zombie attack, but it's cheap insurance to have always attached and it's come in handy while running/jogging/walking with labored breathing during fast moving stages on the range.
Get one and see if you like it....they are cheap.
