I have a few of the Nickel Supra Marburg Germany scopes that I purchased from Jaeger gunsmithing who was the importer of them in the 80's and 90's I even have a couple older Nickels.These scopes are as good as you can get and I have hunted very hard with my Nickel scopes and never been let down.I have had a lot of German optiks in my life and I would rate these at or up to #1 .I cant tell you how many Kahles, Swarovski and Leupold scopes I have had leak or crap out .The Nickels have always been reliable along with my Zeiss'. As for the new ones I cant say but if they are made as good as mine but if they are made by the same people i would bet they are. Leupold ?....like looking through dishwater when compared to a quality German optik (To my eyes anyway)
