Hi guys, I'm tearing my hair out trying to find a ARD/Killflash for my scope

Leupold Mark 4 M1 16x made in the 90's

As per Leupold's site  52292 should work but the interior of my objective lens has fine threading that that particular part does not have.

Could someone point me to the right item for this?

ETA: Went with the MK Machine option, I'll post a update when I receive it thank you Nobody69s!

If you're fine with the ARD mounting on the outside of the objective lens the MK Machining ones are great!

That looks preferable to me actually, to the point I ordered one, Thank you!

They didn't have one for the exact model but they offered caps based off of the Ocular Housing OD, I was able to caliper check this at roughly 1.96X/1.97, so I selected the 1.969 option, I will provide a update once I receive the cap.

Tennebrex  has a selection which include ones for Leupold.

You should be fine with ordering just undersized.
That's what I did for one of mine and they fit great.
