Thanks so based on your list it's proly a remington aftermarket blueprint with 18 tpi instead of 16 tpi....the reason I'm asking is I have a 700 la nd didn't no if I could get it to work. Here's the breech face

Only if your action threads have been opened up to fit normal Rem tenon is 1 1/16-16

Would that 1 x 18 tpi be able to be turned on a lathe to rem factory fairly easily?
I don’t think so but easiest is to contact a gunsmith and ask. If anything you may need to true your action to open it up a bit. I could be wrong here though I’m not a gunsmith.

LRI opens up Rem 700 threads and then Changes them to 18tpi. But a 1” tenon won’t work with a Remington 700. They start larger from the factory at 1.0625” x 16tpi
What is the tenon length?

Not sure he didn't say...my plan if I bought it was to put more threads on the tenon and use a savage nut system or remage to headspace and install

you would have to cut off the old threads and rechamber to make it work with a Remington 700 action. Unless the diameter is larger then 1”
