I have the Kahles and Swaro with TDS, but they are damn near impossible to find, I need another scope with BDC for another lightweight rig being put together for a friend. I have been wanting to try out the Rapid Z, I am sure the reticle does fine, but hows the glass stack up clarity and light gathering wise compared to a Swaro or to my favorite a Kahles? Anyone got some first hand? I have not held the conquest and no one has a local. Thanks brothers.
