There are more Marlin 336 rifles out there without the crossbolt safety than with them. I prefer the lever actions without that cross bolt safety since I grew up without it and I am content to put my rifle on half cock for the safety. That crossbolt safety cost me a deer the first and last time I ever used it. I was using my Marlin Guide gun in 45-70 and I had a big doe at 20 yards broadside in front of me, I had a perfect sight picture and squeezed off a shot. A very loud clank was all that I heard, and the doe kicked in the after burners and was gone. Fortunately, 15 minutes later a bigger doe came strolling buy and I took her. I never engaged the crossbolt safety again. It is not necessary and is over kill.
