Is the latest generation of the SR25 (E2) considered to be as reliable as 5.56 AR's or are they somewhat less reliable? Outside of KAC itself I'm not sure that hard data on this exists so I guess I'm just looking for comments from SR25 E2 owners who have put a decent amount of rounds through their rifles. On paper I think the SR25 E2 ACC might be the greatest rifle ever made but in the back of my mind I keep thinking that a 308 AR will just never be as reliable as a 5.56 AR.
