Always reliaiable weaver top mount rings - Weaver Extension Top Mount Rings

I bought these rings because i needed to mount as 3 x 9 x50 scope on a Winchester model 70. I needed to move scope back some for proper eye relief. I used the weaver chart to choose the right ring height and they worked perfectly. Inexpensive solution thanks to optics planet pricing. Weaver is an old name often overlooked when scope mounting systems are considered. I have used other brands that are good but alot more expensive. For price, reliability,and simplicity they are the best. One more note. I have never had to shim a weaver ring set because heights were off. Can't say that about other major brands.
