Well my son took my AR 223 out of the safe on Sunday to shoot a Coyote in the back pasture but had a problem with the round jamming half chambered when he attempted to load it. I was not home at the time but he told me about when I got home. He said the round was a bear to get cleared but didn't see anything he noticed as strange, so he tried another round and the same thing happened. He had the weapon disassembled on the loading bench (Marine's are real good at that), so I took a look. Well it was clear to me that something was stuck down in the chamber in the neck and the best I could tell, it looked like the last round fired may have ruptured at the neck shoulder junction and the neck portion of the case was still stuck in there. It looked like the rear edge of the case neck was kind of flattened where two rounds he tried to chamber hit up against it. Well to say the least, I was disappointed as this AR is only a few weeks old and we had only fired it on 3 different occasions. Knowing this thing was probably in there for keeps, I wrote my Smith a note and the wife dropped it off to him yesterday along with a Weatherby to work on the trigger. He called me today telling me they were ready to pick up and he fired the AR several times with no problems. I asked him if it was a case neck and was astonished as what he said. He said the thing looked like the tip of a boar guide. I thanked him and hung up. (Now one day turnaround for work on two rifles is good stuff folks) I then opened my cleaning supplies case and took a look at the bore guide and sure enough, the tip was gone past the o-ring. Now I know I should have got that all aluminum bore guide instead of the plastic one I picked up because I thought it would be easier on the chamber.
