The first time in my life my son got me somthing for fathersday and it was a Tasco world class scope that is where the problems becan I had a 7mm mauser I just finished and put thatscope on it God what a peace of JUNK point of aim was everyware 3 inchs high next shot 7 inchs low I change to a old Burris I had and it shoots great. I call Tasco to send it back for repair and was told they would not fix it unless I payed for it. I ask what about the warr. and was told that the scope was made before 2003 and they would not honner the warr. It was not my son fault that it set on the dealer shelf for 3 years. A lesson well learned never never buy a Tasco scope which is now own by Bushnell and they are junk to.
