I'm getting ready to try a new American made precision CNC nipple as sold by a BP dealer here in the U.S.A. I told him that if it were what he claimed it to be then I would spread the word here. He says these are stainless and unlike other makers these will take a #11 cap w/o needing to be pinched. They are Rockwell 45 if I remember correctly and he is selling them for $2.50 each. I have on order 6 for Pietta & 6 for Uberti style threads. If they are as good as promised then is anyone else interested?
