I have a nice Marlin 336 in 35 Rem that makes a fine woods whitetail rifle. Used a Marlin 93 for years and can't get used to the pushbutton safety. Missed a 50 foot shot at a nice doe a few years ago because of the darned thing. The 336 also has the same half-cock safety notch as my old 93. Does anybody make a filler plug that I could install in place of the push button?
