I have noticed that many bench rifle's & even hard core Rail systems use dovetail mounting for optics. There must be something to it vs other systems. I remember Davidson 1/2 x 60 & Kelby,Harrels had rings for em. I even think early RAW has 1/2x60 as I have Harrells & D3 Davidson rings that I use on a RAW. Is it a better way to stay parallel to bore or just simpler to machine.? Seems nowadays it wouldn't matter with advanced machining but I definitely still see em on Rail systems that are very extreme. BR units.
