Distance of tang sight holes

Post by SqHunter » Tue Dec 04, 2018 6:09 am

How far is the rear tang sight hole from the stock bolt on the older 39a? I have decided to have mine drilled for the Marbles sight, but don't know where the rear hole should be.

Thanks!

All my 1951 Version, the 2 holes are approximately 0.475" apart to the best of my ability to measure them. I have a tang sight mounted that covers the rear tang bolt so I had to estimate its approximate location.

Wouldn't you use a longer bolt for the butt stock as one and just drill & tap for the other?

The marbles sight is not designed to use a stock bolt. It came with two screws about 3/8 long. It is my understanding the first screw should be in front of the stock bolt so the rifle can still be dismantled even with the sight attached, but I am not sure exactly how far up it should be.

I can't drill the forward most screw because of the serial number.

That screw set part # includes a longer screw that accounts for the Marble's base height. Here's an idea to consider.

Were it my rifle, I would remove the stock and determine if the SSN also appeared in other places on the receiver. If not, I would stamp it on the side tang. (left side probably). Then I would drill the darn thing and forget about it.

But it isn't my rifle.

If it were me, I would check with my local ATF office before drilling through a serial number. And I definitely would NOT restamp it without their approval. Obliterated serial numbers on firearms are frowned upon, to put it mildly, by law enforcement.

The serial number on this rifle has not been harmed. I am going to drill on hole between the stockbolt and the first number and hope it is enough to hold the sight on. I have been told it is, but we will see.
