I’m going to have to get a set of those Grand Slam Top Mount bases for my Marlin 30-30. The aluminum 2-piece bases are tall and don’t look right.
I’m sure I’ve over tightened a base screw or two before I knew about locktight on mounts. Never had the same problem when wrenchin mx and crotch rockets though.
I assume that your Marlin 30-30 is a Model 336. If so, I have always used the 1-piece Weaver #63B on my Marlin 336s and Mossberg 472/429s. If you use QR rings, you can see down the "trench" of the Weaver #63B and use the open sights if you need/want to do so.
