Rick, you're referring to the Azodin triad barrel (at least that is what I think it's called). the few guys I know that owned a KP hated the barrels as they were prone to ball breaks. It was commonly attributed to the o-ring detent. Whether or not there is truth to the theory is debatable, I'm just passing on the limited knowledge I have.
