Looking to put 30mm glass (SS 10X42)on my Swiss K31. Am looking at the St Marie style STEEL clamp-on mount from SwissProductsLLC. It has gotten the best reviews from the masses so far (anyone have a used one for sale ?). However it uses a 3/8 Dovetail feature, most likely because of the tight clearance issue for brass ejection. Is anyone aware of a quality set of "tactical style" low - medium rings that fill this bill? Thanks In Advance !! Joe
