Hi all,
I have a 1948 mfg. model 94 flat band carbine in 30-30 which has receiver sight mount holes. I have found they are 6-48 tpi and measure out to approx. .410" apart. Would like to know if this is the proper measurement for mounting various receiver sights such as Lyman or Williams? I was told by knowledgeable people that drilling and tapping for receiver sights was a factory option at the time my 94 was made. Thanks for any replies!
