First off, I am not looking to spend a ton. I have an old Weaver K4 scope manufatured in El Paso. The reticle is a "post style", which I do not care for. Is there a company (or an old timer) that anyone is aware of that has the ability to change reticles to a simple crosshair? I would just like to be able to use this for my purposes. As it is it is of little value to me in its present form. Thanks.
