Tiffer,

Just measure my Eclipse bodied pump. The detent is 45mm back from barrel face, as in where barrel screws up to, and 38mm up from the the bottom where grip frame mounts to. I don't think it needs to be 100% accurate to work ok. The thread size is quoted 3/8 - 24 UNF. If the detent hangs into breech too far it'll chew bolt to bits. This can be prevented by trapping an o-ring under the detent.
