Tokguy: I bought an S&K no drill mount to try on my Krags. It actually was a far better fit on my Norwegianicon Kragicon than it was on the US Krag 30/40. On both rifles you need to do some wood removal to allow the S&K Split ring to fit into the stock. In both cases as well the scope (a 40mm) prevented use of the safety and would require you to grind off 3/16" of safety lever or raise the scope....not easily done with the S&K mount. I have it currently on the US Krag and will try this at the range but am not sure if the mount will remain stationary with the 30/40's recoil. The S&K fits much more snuggly on the Norwegian Krag. I have also ordered a used peep sight that will mount on the US Krag without drilling any holes. This may work well enough for short range hunting for deer or moose and allow me to put the scope onto a Norwegian Krag for longer range shooting. Good luck with yours.
