I've always had good service out of Weaver scopes. From the El Paso's til now. In 2008 I put a 3-10x40 GS on a .270 Win M70 Fwt Classic I put together and it's doing fine. It's compact enough,does a very good job in low light,clear edge to edge image,tracks perfect,and holds it's zero. I won't ask for anymore than that.
