You're right , I don't really know much about the scope except that I bought it from a coworker and that it was on a 44 mag. The person I got it from also gave me 50 rd of his hand loads to check it out . Seemed to be good several people have shot it and were somewhat impressed with it's accuracy . Just a few days back we were busting gallon milk jugs filled with water at 200yds . Going to try it again with better rest .
