Very informative for those who are buying a new stock
No, this is not very informative. It is confusing at best and contradictory.
The top image says the Mil spec tube has a diameter of 1.146" and the commercial tube is 1.170" - OK, Mil spec is smaller - got that.
Second image shows the commercial tube dimensions and they confirm the information in the first image - cool, got it.
The third image shows the dimensions of the Mil spec tube and is contradictory in that one diameter measurement is 1.148" and the other is 1.185" - OK, now I'm just confused...
The 1.185, on the lower schematic, is referring only to the width of the threaded portion, which is wider than the tube portion and nothing else. Buffer tube diameter is only indicated in the cross-section portion of the picture. Also the "slant back" is not always present on all commercial buffers, but is never present on Mil-spec.
Hope this helps!
Write something about yourself. No need to be fancy, just an overview.
