I was sighting in my little .243 CVA single shot at the local range a few days back and the guy next to me had a fancy (don't know brand) AR15 type .308 and was all over the place on the target. As he shot he kept going farther and farther right until his military rear open sight adjustment was all the way to the left. I asked him if he was squeezing the trigger and he said normally he was a good shot. His barrel was extremely hot and I think he actually warped it from shooting so much.

My thoughts (former metallurgist for a transmission company) was with a military type rifle that would be used in combat the barrel should be properly stress relieved after rough gun drilling and machining so that when it got hot in combat it would not later stress relieve (bend) during shooting. I think this guy bought a lemon.
