Just tried to mount the ML-12-05 on my new 1894 Marlin. The screw hole spacing for the front ramp was right but the back of the ramp hits the front barrel band. I've got a note into Bo Wallace for help. I don't recall this problem being discussed before but I could have missed it. Kind of disipointing. I may try to sight it in tomorrow with the bead that's on it. The receiver part fits fine.
