    I purchased a custom rifle for my wife last year. It’s In the style of a Southern Mountain Rifle, anyhow she has shot it quite a bit lately and it’s now in need of a new nipple. I’ve looked through my stuff and cake up with several different sizes of nipples.... none of which fit. So I measured it and came up with this size... the shank where it is threaded is .232 thousandths with 1/4 by 26 threads. Does this sound familiar to anyone? I looked through Tracks stuff and found nothing that matched those measurements.. need help on this one. I have thought about drilling the drum and rethreading it with 1/4- 28 threads which is more common.

    Do not drill and rethread the drum with a 1/4-28 thread. It is too close to being the same as the thread that is already in the drum so rethreading it with that size tap will only totally destroy the existing threads and leave you with partial threads that can easily fail.

    The .232 diameter is very close to 6 mm which is .2362". It is common to find the outside threads slightly smaller than the "size" of the thread.
    24 threads per inch equates to being a pitch of .0417 inches which is almost the same as a 1 mm pitch. (A 1 mm pitch is .0394 inches between threads).

    With all this in mind I would say your nipple should be a standard metric 6 mm X 1 mm. CVA and Traditions uses this size thread for their nipples on many of their rifles.

    Zonie is correct.
    6mm x 1.0
    (0.236” x 25.4 tpi)
