I was wondering what type of reputation the older (later 1980s/ early 1990s) Triple K magazines have. I have an oppertunity to buy one of their hi-caps for my Marlin .22 semi-auto, and it seems like a steel mag would be a better prospect than the Ramline plastic mags- which I am afraid those could be fragile, considering that they are 15+ year old pieces of pastic- with plastic mag catches and feed lips.
