I tryed the weaver "it sucked"and B sq. "it also sucked",ended up with the S&K.Rock solid,but it does replace the mini 14 rear sight like the Weaver,but its more solid and a better design than the weaver IMO.Have shot over 1200 rounds and still holding zero,but you do have to remove scope and mount to strip for bolt cleaning"if you take the action that far down"I would buy the S&K again and not look back once.Aldo
