I am with Kilco, I have been shooting AR's for 50 years if you count the M-16's I poured thousands of rounds through in Vietnam and I have never changed bolt rings. I currently have six AR's including one 6.5 x 39 which is my fav. If they are breaking apart I would say they are poor quality, get some real mil-spec rings.
