Meh...I like my direct impingement. That ammonia smell let's me know I'm alive!
I feel the AK47 is not as reliable without cleaning as it's near mythical reputation makes it out to be, nor do the feel the AR15 jams every time you sneeze on it unless you get it as clean as Intel's CPU Fab facility. I believe the gas piston AR is a solution looking for a problem. I've seen ARs push thousands of rounds between cleanings by simple squirting some CLP in/on the BCG. I am, however, glad that manufacturers are continuously looking for ways to improve the worlds greatest EBR*.
