Popular ways to mill sights off surplus arms in the 50's & 60's?
Ok so I have this 1917 that started life as a usmc rifle. It was then bought by my grand father and turned into a 300 h&h hunting rifle. He then didn't like that so it became a 308 win target rifle. The rear sight was milled off and I'm not sure what the rear of the action was milled to I thought I read one time in a book that it was popular to machine the rear of the action to accept Winchester mod 70 bases or Remington 700 bases. It doesn't look like my 700 but I don't have a 70 to look at my dad does but for some reason he won't ship me his super grade varmint rifle.
So I ask here was the mod 70 a popular way to machine a Milsurp rifle back in the day?
