Boys I need some help.
My old Mauser came with a Williams rear sight but without the aperture.
I've got a spare Lyman but it won't thread in more than 1/2 a turn, or so.
They are supposed to be threaded the same. 7/32-40
Any ideas short of chasing the threads?
It might be simply a case of too much paint in the threads.
