After reading through these forums a bit, I have decided to purchase the J & J ceramic barrel for my 98. My question is: I have checked several places selling J & J's but I have found one advertised as J & J Performance and one as J & J Precision. Are these the same company and just a typo by the seller, or am I viewing two different barrels? I cannot see the J & J logo on the seller's photo that advertises it as J & J precision and am a little worried that I may purchase the wrong barrel even though in the description it describes a J & J ceramic barrel. Any help would be hot.
