Called BAD and the guy I talked to asked me allot of questions. Glad I know something about rifles. Even had me put it in my forged AR15 and it was tighter in that than my billet gun. Sending me another center section will see. On a positive note shot it yesterday NO FTF or hickups at all. Ran very smooth. Had the block turned down and it was dumping brass at my 2 o'clock. Very happy with how it shot. My son shot it and said it recoiled more than my 12# bolt gun in the same caliber. I don't think so but then again he may be jealous. Will get the photos up soon. Different grip with no palm swell being put on today and hopefully my replacement center section for my BAD ASS will be here.
