I'm planning to get AO ghost ring sights for my 1894 LTD, but on the cabelas website it says "Fits a Marlin 336 or 1894 model rifle with 3/8 inch dovetail in the barrel." Does that mean they will work on a marlin with a ramp front sight.
It has to do with the height of the front sight. The ones designed for the rifles with a front ramp have a shorter front sight. The ones the mount directly into a dovetail on the barrel are much higher. If you call the company directly they will send you the proper height front sight.
