The only old wives tales I used to really believe was that the AR-15 was insufficient as a service rifle. Over time, after handling many alternatives (M14s, Tavors, VZ58s, Type 81s, etc.), and realizing what capabilities it brings to the table (mainly quick repeatable shots, which is in a reliable, light weight, easy to maintain platform), that changed for me. Its going to suck when I have to turn mine in.
