I am trying to find a rail for a Sporterized 7.7mm Arisaka that has been
converted to 300 Savage. I bought it at a Military Surplus store for $130.
It was drilled and tapped, but who knows when !?
The receiver is straight and level front to back and has holes pre-drilled
and Tapped for the Weaver screws.
I measured the holes with my trusty digital micrometer.
Having the dimensions of the drilled holes doesn't do me any good, though,
as nobody knows where to look.
All the rails are made for specific rifles and who knows what the guy who drilled
these holes used for a rail ? !
All the stores where I can look for rails have the damned pegs behind the
counter and clerks who are as dull as a fence post soaked in the rain.
I have found something that I want to try, but it requires longer screws
than come with Weaver rails.
My question is - what are the specs of the screws that come with Weaver rails ?
I think they are Metric, but am not sure - I am not a machinist and am trying
to keep the expenses at a minimum !
What thread size are they and where could I obtain that thread size, but
longer than what Weaver provides ?
