ASM Remington 1858 Nipple Size?

[Patrick Henry Brown]

Can anyone tell me what size nipples the ASM Remingtons used. I have a pair and would like to change to Treso nipples. Thanks.

I have a couple of ASMs, one had a nipple missing when I got it, and couldn't get replacements from VTI.   Off hand don't recall what the threads on them are.  But I think the folks that sell Tresto Nipples would know.  Just tell 'em you want nipples for an ASM. 

Good shootin' . . .
