i bought myself a sightron 10-50x60 scope for right now i'm using a set of luepold extra high rings but want to go with a 20moa base and pic/weaver ring but i'm concerned about the scope hitting the barrel(bull barrel no taper) right now i have about 1/16th" gap between scope and barrel and with a 20 moa base it would cant the scope down in front. the other option is to use a 0moa base and buse signature zee rings.
