Well if it’s Diemaco it’s for a mil-spec tube. The hole is for the stock position indicator. Some buffer tubes have numbers on the top of the tube corresponding to stock position (eg 1-6). It’s so you can easily move the stock to the desired position.

It has nothing to do with a position indicator. The hole is simply there as a result of the manufacturing process.

That just conveniently lines up with laser engraved receiver extension tubes...

Op it is normal. It is for milspec receiver extension tubes and no it doesn't lock up tighter than a nun on easter sunday. Interesting tidbit. Hk416 stocks have a hole in the same spot.

The only reason that some companies started marking their tubes is because the hole is there already. Not saying that the markings aren’t a nice feature, just that they came, what? 40 years or so after the fact.

Leg is correct. The hole is there to facilitate assembly of the spring-loaded Locking Lever. It was (much) later made use of to indicate the Buttstock position on laser-etched Receiver Extensions/Buffer Tubes.

If you're cloning a C7/C8, that's not a thing ;) We've got 4 position tubes as standard, or 2 position if you're doing up an old C8.

A quick note on buffer tubes... I have disassembled alot of original C8's (some new in the bag). All have had 2 Pos buffer tubes, everything from the pre-production 85, 86 and 87 rifles, the 92 contract as well as the 97
dated ones.

I have never seen a 4 or 6 hole tube on a C8 with a 14.5" barrel. Not to say they are not out there, but they are far from the norm.
 
The older C8s all had two position receiver extensions unless they were repaired with the four position ones when the C7A2 was issued with the new extensions. The C8s started using the same four position extensions as the C7A2 when we started getting C8FTHBs/C8FTHBA3s/C8A3s.
