It is funny that people who are so quick to run down the REP Marlins either forgot or didn't know about the dreaded Marlin jam that was common to the JM Marlins. Fixing the Dreaded Marlin Jam
Yeah the carrier is made of a metal that is too soft so that the snail cam on the lever starts to wear groove... but the new Remlins also have this problem as well, too soft a metal is still used on the carriers.. I purchased brand new carriers for my lever guns a long time ago but was also thinking of welding in a piece of hard metal and filing to fit so it wont wear out while I still live.
